On your account I am worse off with one person in my house, albeit marginally, and I am vastly worse off with lots of them in my house. In other words, on this account people are negative-value, and I am best off living alone in my house while the homeless people stay outside.
At some point it seems worth asking under what conditions (if any) an additional person in my house provides positive value (for example, if they can provide valuable labor or entertaining company).
It also seems worth asking whether and how we can make those conditions obtain more generally, and whether the cost of doing so offsets the value obtained by doing so or not.

I think the most popular solution is rent but it’s hard to generalize to nations
Rent is a popular solution, yes. So is an exchange of labor (e.g. spouses, household servants, children). The latter is easier to generalize.
