Do you know how much work it is to live unhoused? How uncomfortable and dehumanizing? If you are completely without shelter, how it is after it rains, or the air is choked with smoke during fire season?
It seems like you have just one explanation for everything here. When there's a problem, it's because of some moral failing that has to be punished. The publication you reference is telling.
Your attitude toward both Roma and unhoused is an outside look in, entirely through the lens of criminality. There is no understanding there. You are missing the big picture, the why behind all of the things people do.
If you really want to scam people, you start an LLC and live comfortably off of other people's work, like, you know, rich people do.
