Any space rocket can turn the whitehouse, the Kremlin or 10 Downing street into a crater withing 30 minutes, with minimal chances of air defence to stoping it. If we start handing out starships to random shady conpanies registered in tax heavens, 9/11 will look like a peacefull day in comparison
Space will be rounding error on suburbia in emissions. At this point it's necessary because population and resource consumption growth has exceeded Earth's footprint by quite a lot. We need people and resources moved to space in the long run.
The military sucks as a funding source morally, but it is as big as you can get as a practical/politically achievable one. Where else can you get a trillion dollars? We need asteroid mining, space habs, launch loops to get humanity to space.
GW has to be addressed through urbanization (centralize people in cities), electrification of transport, artificial meat, synthfuels for long haul transit, alt energy for power gen. I'm not saying we'll make it with those, but at least all of that is somewhat underway.
Consumer culture seems to be defraying birth rates. So while consumer monoculture is bad in many ways, if it perversely constricts population growth then it's good. Kind of like if the oligarchs effectively starve everyone of money needed to have big families... it is perversely good for the environment.
But you're talking to someone who's political alignment is "despotic environmentalist".
They'll be highly expensive and highly vulnerable targets. You can't armor a space station.
Traditional naval theory is that you can build a battery onshore 10x bigger than the one on a battleship. Things change when you are in space though. Missiles have to escape the gravity well. Lasers have to get through the atmosphere. Sure it's expensive to get up there, but if you have space superiority, you do have certain advantages.
Starship will represent a total paradigm change in space superiority on economics alone. I'm surprised China and Russia aren't loudly complaining about this. It would enable an actual space fortress to some degree. 10 billion dollars for a 1000 tons of hardware in space? Um, that's less than an aircraft carrier.
An aircraft carrier is 100,000 tons...
As stated, space tourism will be HUGE. If 5g/ticket is true, I mean, who on hackernews wouldn't go on that trip? Even if 1% of people in the world take only one flight that in our lifetime that's 80 million people.
How many people want to do the Red Bull parachute from space? I would guess: A LOT.
Just wait for the private Starships. Hey they should be cheaper than megayachts. Show up at starport, anywhere on earth in an hour.
My biggest dream: starship payloads to get a moon-launched 1.5 million ton Project Orion pulse nuclear ship. That is serious equipment payload to do real asteroid mining. One heavy metal/rare earth metal asteroid will pay for that round trip.
But really, I'd argue we just need to enable:

Why fly it out of the gravity well? Need material? It's out there. A bit hard to catch, but it's out there.
