I can't say I agree, this feels like a very uncharitable reading of his/her posts. Unless it was edited in after the fact they even said "You're absolutely free to believe either way, and I don't want anyone to force you to do anything."
While it would be insulting to call any individual person's preferences a result of brainwashing, I don't think it is a stretch to say that at a societal level preferences are shaped by mass-media and advertising. Improving access to and making people aware of less resource-intensive forms of comfort doesn't have to come from an authoritarian place. One of my major motivations for seeking out a more walkable area was urbanist YouTubers extolling the benefits. I suppose one could argue that things like bike lanes are hurting drivers but if a city's transit priorities stem from local politics and preferences I don't think it can be reasonably argued that making any particular transit method a priority is more authoritarian than another.
> In practice, comfort is mostly a function of stuff.
No question that it is a variable for most people but I'm not sure I buy that it is the most dominant one. All other variables being excluded, time to do what I want is at least as important for me as stuff (luckily I like my job so time/money aren't usually in conflict). And I think for many people "stuff" like cars and nice lawns aren't inherently drivers of comfort, but rather just possible reifications of goals like "pretty yard" or "fast/easy transit," both of which can be realized in less resource intensive ways. For the yard example, that might be a native garden or xeriscape (in some cases there are rules against these, which actually goes against freedom imo).
I don't personally believe people when they say that anyway, so I'd have taken the same stance even if the post had said that originally. Collectivists like that are never happy if people can make their own personal choices. That's why we now have government mandated phase-outs of liquid fuel vehicles on the horizon whether individuals like it or not. They campaign and bully until they get what they want, which as picture states very clearly is bans on anything convenient in favor of non-private property (n.b. they're fine with swimming pools as long as they're shared pools, and already admitted their actual motivation is dislike of capitalism not a belief that restricting golf will actually achieve anything).
