Sorry, I had been attempting to strike a nagging tone more than a bragging one: to put it more baldly, homelessness is a (collective) choice.
[I voted with my feet for this society. That took me a couple of years to learn a language, and a few more to learn a culture, both of which seem to be much shorter timescales than I expect change, whether driven by pollys or by people, to happen upon in my old, or other anglophone, societies — even with nagging.
If you think I have more effective means than nagging, please let me know what they may be. I am generally a fan of mutual aid and direct action, but at this point believe that occasional nagging with an existence proof that there are functioning alternatives, however indirect and unmutual it may seem, is still as close as I can approach those ideals while remaining effective]
My relatively stable high trust society has bunker space for more or less the entire population; if the world goes to hell I'd much rather be* among people who (even on our right wing) habitually put solidarity into practice than be worrying about generators, ice augers, and looters.
* one of the best pieces of advice I ever got, related to skating to where the puck is going to be: "if you know where to be, you can let the young guys run"

If you can't trust foreign governments any more than they can trust you (you are the foreigner to them, after all), why not just divvy up the world into a bunch of "hunger games" districts and use gunboat diplomacy to keep them in line?
Ancient Aliens ought to be required viewing in schools, because they are very careful to employ enthymeme and reported speech to make a series of statements each one of which is technically true, yet have implications which are false. Gaining the skill to recognise when these kinds of claims are being made is, I feel, essential for the electorate in a democracy.
