I agree with most of your points here and had to give you an upvote for this one.

The last bit about how some things are "good in theory/not in practice" is a phrase I've heard a lot, but it often ignores the systematic structures in play to actively prevent those things from working in practice.

Take communism for example. Cuba was very near being functional and working in practice, if it weren't for the west actively interfering in it to ensure it didn't work and that this [anti-communist] rhetoric would be viable. Good in theory/not in practice just lacks nuance imo, but i understand what you're getting at and we don't need to get into it as you've gone into plenty of depth already and I don't feel like discussing it further.

Thanks for getting back on track, I feel like people (including myself!) were misunderstanding your initial point but I feel like this comment represents it better.
