> it's still supposed to be enjoyable. Clearly homeless people in the game are impeding some peoples enjoyment and it's a problem that is not obvious to solve.

This tough boss is impeding my enjoyment of this RPG because I can't mindlessly beat it.

This tough level in an FPS is impeding my enjoyment of later levels because I can't beat it.

I can't place first in this tough racing track and that is impeding my ability to enjoy it.

Homelessness is a challenge to approach however you want. It only becomes a problem in huge cities with rapid middle and upper class expansion, ie, the late game. So if you get stuck and have a skill wall in front of you to overcome but can't, that is not a deficit of the game, that is the whole reason the game exists, to impose challenge and difficulty to overcome.
