The anger isn’t (necessarily) for the rich person who housed people. It’s for the system who left people homeless in the first place, the system that will put those people back on the streets if they don’t pay rent/property taxes/whatever other fee people have to pay to exist, the system where the solution is literally just “have rich people pay their share and almost everything will be fixed” but for some reason the people in charge can’t (or don’t want to) figure that out.

You conflating anger with the system with anger for people getting houses is disingenuous.
