In a socialist system? Money. People with more demanding or specialized jobs would have more purchasing power. That's it. That's how it currently works in most socialist countries. People with more money purchase nicer housing.

In a completely moneyless society without any notion of property ownership? A completely post-revolutionary society with altered concepts of commodities? Who knows, those people in the future would have a completely different conception for what the meaning of life is. I certainly have no idea how they'd distribute stuff. People by then might not care about living in lakefront housing, or people might have a different concept of housing entirely. People might rotate out when they stay at a lakehouse. There's no pre-designed system for this because the people in this hypothetical scenario would have different material conditions and desires than we do now. Ask an aristocrat in the year 1034 about how people in 2024 would acquire and use desirable farmland. That's how far off our perspective is here.

My only prediction is that people in the future simply wouldn't care as much. I'd hope a communist future would have much more chill people overall who might view the entire world as their home.
