There would just be less housing. Construction workers are workers too, and as much as it sucks, they aren't going to put $50k of their own labor and materials at risk so that a person living paycheck to paycheck can own a home, regardless of how noble that pursuit might be.

I also support radical action to end housing shortages and homelessness, and believe secure housing is a fundamental human right. If the government wanted to buy my properties at cost, using my own tax dollars, and gift them to those in need, I would support that. If they wanted to turn my current home into high density housing, I would support that. I am doing many things on my own, both through advocacy and direct action to address the real moral problem of housing. Unfortunately, I have no interest in being a smug slacktivist, so it often seems like lemmy doesn't have any interest in my ideas.
