This isn't a big problem for roads, sidewalks, or the library.

Roads aren’t really free: you need a car or at least a bike.

Sidewalks are free, but they are usually unpleasant or inaccessible. In places where that isn’t true, they absolutely get trashed by litter; some even spit on the sidewalk.

Libraries are seemingly free, but getting a library card often requires you to provide several forms of proof of address, including evidence of paying rent or property taxes. So they aren’t truly free.
