Whilst it's not a crime not to have a house, providing housing via free buses is a very poor way to address people who don't have houses, and it has an unfortunate side effect of pushing people who would otherwise use public transportation away from using it.

You see this in public libraries in major cities. They're open to everyone, so they become shelters of last resort for homeless folks. The large presence of homeless people discourages the public at-large from using the library as a library. That in turn weakens the political will to continue funding libraries.
