It's all well and good to postulate a free society, but do you have any idea what a free society actually looks like? (Neither do I, by the way.)
But from our point of view, what's the practical difference between being forced to comply with a King's royal edicts and being forced to comply with a bunch of politicians'?
Cartels can't be maintained in a free society. We know everyone participating in one is a scumbag, and the more lucrative the cartel's position is, the more motivated the participants are to betray the others (because there's lots of room for competing on price and taking away all the captive customers, thus making shitloads of money).
Cartels are a difficult thing to break. The light bulb cartel for instance still exist, even though it has officially been dissolved: light bulbs still only last a couple thousand hours, despite the existence of designs that can last 10 times longer. (Heck, that's one of the few things the centrally planned economy of the USSR got right: long lived light bulbs.)
Strength lies in numbers. Fascists knew that, popular movement know that, and cartels know that. Betraying the cartel is to fin yourself alone. The financial incentive may not overcome the need to be part of the same team. And sometimes, as is the case in the light bulb industry, it is not clear that you could actually take away the cartel's customers: light bulbs are fairly cheap, at face value. It's the planned obsolescence that's the real cost, and that cost is not disclosed to the customer.
You can only make your purchase decisions based on what you know. If the cartel is based on deceit, rather than on price regulation, it can be difficult to convince people based on durability concerns. People don't care about sustainability, because of hyperbolic discounting. (Why do you think we're trashing on the planet with little regard for future generations? It's not because of our rulers. It's because we just don't care about the future as much as we should.)
If the guy is selling X for half the cartel price, and can point to the cartel members and tell people how they've been screwed by them, what do people care aboit what the cartel scum is saying anymore? Nothing. They'll just buy X for 50% cheaper. You know you would too.
Who are trashing the planet? Ordinary people, or big corporations who've paid politicians off to let them pollute? What about militaries all over the world? Do you really think ordinary people are the problem here, or govts the solution? Really?
> Who are trashing the planet?
Everyone of course. Some people more than others, and as you suggested, some people are more responsible than others. But in the end, we're all caught up in this system. Heck even writing and reading this comment takes energy, and sits on top of one of the most polluting industries (computing).
We both know how cartels work. I pointed out that cartels don't last without state support. You don't feel like accepting that, just like you still haven't addressed my point about rulers.
Cartels are created and maintained by governments through prohibitively costly licences that are just denied to pesky outsiders that would actually compete with the other producers.
We're not going to get anywhere if you keep side-tracking the conversation, but that's exactly what staunch statists always do. Why? Because they can't handle reality.
