You're just following what feels like it would be good for the environment (and maybe it is good for your local environment) but isn't actually impactful at a large scale.
You write eloquently, but futilely.
Instead, what if it's a mindset: Doing such things, and 1000 others, some of them vastly more important than others.
And you can add to the list (instead of just saying "it won't work").
E.g. high car gas taxes, so there'll be trains, buses and bike lanes instead for everyone.
That doesn't make any sense why would we make sacrifices that are not important.
The whole point of a capitalist economy is to “route around inefficiency”, in the same way the internet is designed to “route around damage”. Any single player or even a large contingent of players, who act inefficiently, are only increasing the alpha available for another player to exploit.
“Inefficiency” in this sense is anything that doesn’t maximize personal benefit - profit or other quality of life. Anything that is legal according to the rules of the game (or tolerated by society) is going to happen whether it’s you that does it or someone else.
The only long term solution is that if this is what needs to happen, we have to encode that into “the rules” so everyone plays by that rule. Personal recycling or personal consumption reduction does nothing at a social level, and in fact is pushed as a deliberate stalling tactic to avoid and stall those political actions which could have a real impact.
This is also the problem with bitcoin - any one player choosing not to participate in mining only increases the reward for the remaining players who will continue to participate. If there is only one person on the planet willing to mine, she gets all the rewards. So simply choosing not to mine does nothing, you’re just transferring profit to someone else.
Humanity has already built the first AIs, they are emergent paperclip-maximizers encoded into the bylaws of corporations and market structures. And they will route around any attempt to un-maximize paperclip production according to whatever levers we continue to give them. If you don’t want people to eat as much beef, you have to build that rule into the system, it’ll never happen due to personal-level changes in behavior.
Governments can alter the rules of the game we play and they are (indirectly) controlled by us, as least in democractic countries.
similarly, even a country-level tax, you're only making it cheaper for other countries who don't care. We saw this play out with Russian oil last year - banning it from the West didn't make it go away, it just made it cheaper for certain other states to import it. The commodity market is global.
The fundamental point I'm trying to make here is the "capitalism routes around inefficiency/morality". That's what it's designed to do, in the same way the internet routes around infrastructure damage (or censorship etc, which is fundamentally infrastructure damage). By taking a moral stand, you only increase the alpha available for other players to exploit.
These "individual moralistic stand" approaches like personal-scale recycling are inherently less effective than taxing producers, or outright bans. The reason they are pushed is because they are ineffective, and because they stall out the political will to adopt real solutions that would be effective.
(E.g. india did buy up russia’s oil cheaper, but if there would have been a carbon tax in the eu with serious tariffs on products made in a not eco-friendly way, their usage might not have increased as much)
that is the observable impact though. perhaps the bitcoin example is more straightforward - if only one person on the entire planet is willing to mine, they get the entire block rewards of the entire network.
this is an extreme example, but if you have a small number of corporations who don't give a shit about environmentalism and pursue maximum profit within whatever the law allows, you get to pretty much the same result. People doing good in one area only increases the alpha available for another player to exploit.
capitalism literally is the removal of morality from economic planning - by making it about personal interests and profit, you ensure that if one player has those uncomfortable morals, that other players will take care of the problem and ensure maximum profit is pursued regardless. It's an Autonomous System designed to eliminate morality from the field of economic activity.
When enough people change their behavior, that can have an effect. And I suppose you're right that that effect is smaller than what one would hope (for the reasons you mentioned), and laws or taxes would have more effect
Further, even if what you advocate isn't exactly harmful, just neutral (ie eating local vegetables instead of imported, nevermind that the carbon footprint difference is negligible) wasting valuable political capital on useless gestures is objectively wrong.
So do you want governments to legislate that you must live with your parents? Or that you must not eat meat? Otherwise it's fine and good that a small share of the populace will make these choices on their own, but we need an order of magnitude more.
Oh how I wish I could just bring a reusable bottle to some dispenser at the store and refill directly. Milk, common juices, soaps, etc. So many bottles going into trash/recycling all the time.
It’s not going to be politically feasible since 99% of people don’t want to live that way. Thus we have to pursue alternatives.
Maybe technology will help us achieve that last minute stop we so need, but we have to start somewhere.
But do we really need to be able to order some bullshit plastic shit from China for 2 dollars? I think it is only fair to give up that for local production, even if that costs 10 dollars for the same thing. Similarly, do I have to eat argentine beef in Europe? Sure, make it available for a hefty price for the rare occasion, but it really should not be generally available. Fruit that is local and is out of season? Don’t import it from Peru, simply wait for it to be in season, or buy some product that was made locally when it was in season, like jam. Strengthening local production would already massively decrease the number of ships we need for minimal inconvenience (hell, it might just be beneficial for the local economy). Do I even have to eat meat each day?
Similary, why don’t we ban most kinds of single-use plastics? How often do you buy milk that you plan on drinking while you walk somewhere? Couldn’t it be stored inside a container you have to bring back to the shop the next time, or buy again if not? Hell, most liquids meant for drinking could easily come in a few sizes of these reusable bottles. We have goddamn shops that can auto-subtract your bought items simply by camera imaging, don’t tell me we don’t have the tech to safely and hygienically refill containers, something we had 100 years ago.
As for societal change: do my parents have to live in a separate house with way too much space for them, having them see their grandchildren only occasionally (making parents having to pay for babysitters)? Only so that they can later be cared for by some random person? Sure, not everyone has parents worth living together with, but this tendency that it is somehow a failure to not move out of your parents home is imo very harmful to everyone involved - parent not having enough self-time, grandparents being alone, slowly deteriorating mentally, children not seeing grandparents enough (also, parents having to figure out parenting from zero).
These are not big sacrifices, but we will do them, one way or another. The question is, do we want to do it with self-agency, or let nature run its course?
