Ever heard of the bed of Procrustes? Porkies loved to use that analogy against socialism. Yet another instance of reactionaries inverting the truth completely.
You know, if you begin a soial media post with a believable setence from an oh-so-oppressed lumpen and leave the punchline to the end, odds are high that it will go viral. There's an entire machinery at work, and not just bots but a lot of miserable desk jockeys too, which does nothing but spam and shit the internet up all day, not to sell products but just to try to shift public opinion. Sometimes they fall for a well-crafted bait like that.
I have been considering the notion that population density past a certain point is inherently and unavoidably harmful to welfare in that way which is hard to describe. This isn't a rare notion, but I do think that the limit is way, way below what most everyone thinks, and cities with roughly 1m people are already way past it. In developed countries, this harm is offset by the high living standards, so we don't even notice the harm exists at all.
At some point, even if we manage to create a libertarian socialist society, population management will have to be enacted at some point, whether we like it or not. Population can increase at rates far faster than services, economy etc., and there's bound to be a cap after which they can't be expanded while population still can. This is obviously not a sustainable situation. Japan is famed for the orderly functioning of public spaces, yet Tokyo is so congested that its subway system has workers whose actual job is to push people into the train during rush hour so it fits as many as "humanly" possible.
