ELI5:Why is vagrancy a crime?

and why are poverty and unemployment illegal if both having no money and no taxable employment aren't necessary to support one's self without impeding on those who have both money and a taxable income?

Vagrancy, poverty, and unemployment are not per se crimes, however the law creates additional problems for people in such a condition.

The reason urban areas tend to crack down on homelessness people is because they create burdens for the city and produce nothing in return.  This is unfair of them to do, but it is perhaps equally unfair to jail or fine them for it.  

It is not a crime to go rambling in the forest or to homestead.  But these tasks are harder than panhandling.  It is entirely possible to chose a life of homelessness or poverty without running afoul of local laws.  But its increasingly complicated and it's practically beyond the means an d skills of the typical destitute person.
