Right now, only the wealthy can really risk things.
Ideally we'd just let more people live closer together like they want to, but the elites won't let more people get close to them.
Often because there aren't any good jobs there. With UBI entrepreneurs can self-select and live in places with low rent and weak job markets.
I think we should have robust social housing, as in Vienna or Singapore. But one thing that both places do that we do not is allow for far more housing to be built per person in high-demand areas (i.e. pricy areas). Their defining characteristic for affordability isn't so much the social housing, it's that they build for everyone as if housing were a human right, rather than a financial investment vehicle like we treat it here by enforcing scarcity.
To the extent that there is a "free market" it's only on existing housing once it's built. For existing housing, we let the wealthy do whatever they want, and use their market power to buy whatever they want, including hoarding it. However, it's only because of housing austerity in the building of housing that this real estate becomes such a sought after commodity. It is only through scarcity and austerity of building permits that continued financial climbs are guaranteed.
Most of the political spectrum in the US has housing completely wrong, and thinks that everything is going to be OK if they can just keep the "wrong" people out. Instead, we should adopt radical inclusion and welcome all people, and adopt the true belief that everyone deserves housing, every single person. Not just the cool ones, everyone. That is, unless we want to continue the current meatgrinder of capitalism. Eviction may be the blades at the end of the grinder, but the auger is the housing scarcity and exclusion practiced by nearly every single person in the US.
If you don't need to chase a high income, you can move where there's cheaper rent and try to innovate there. Assuming that you don't need any of the spatial resources of the expensive areas. (A big if... but perhaps you can grow your idea then move to the areas with lots of capital.)
