Yes, we had and enforced vagrancy laws. It didn’t use to be expensive.

Vagrancy laws were ruled unconstitutional by the Supreme Court almost 40 years ago: https://www.washingtonpost.com/archive/politics/1983/05/03/s.... A bit of reflection will suggest the possibilities of abuse under them.

Indeed, but a bit of observation shows me the abuse that happens without them.

Perhaps if you were poorer or of a disfavored ethnic group, observation would show you the abuse that happens with them.
