Preventing people from sleeping in some manner is just inviting unintentional consequences.

I don't think the consequences are unintentional. Torturing a homeless person by continuously harassing them for trying to get sleep, then recording them lashing out at a city worker or police officer after they've snapped, produces a set of video content that can be spread across the internet and used as kindling to turn the housed public against the homeless.

In the same way Project Veritas existed to harass and extort voting rights activists and health care centers, these laws and the associated anti-homeless activist base are going to be used to justify mass round-ups, imprisonments, and police executions of homeless people.

This is real actual fascism in practice.

People being homeless is a failure of society, not an individual.

“If You Born Poor,It is not your mistake, but if you die poor,it is your mistake”

― Bill Gates Sr., Showing Up for Life: Thoughts on the Gifts of a Lifetime

Should be noted that Gates Jr was born into a family of millionaires, with a mother who sat on the First Interstate Bank of Washington's Board of Directors and a father who was a founding member of the law firm PGE. If you want to talk about individuals who might be responsible for homelessness, these two are a good place to start. They've been "philanthropists" for most of their adult lives and commanded billions of dollars in charitable donations. But the their tenure in these non-profits and committees have yielded rising poverty, declining standards of living, and enormous new personal debts.

The folks who have horded the lion's share of the national wealth firmly believe that they aren't responsible for the consequential inequity and bankruptcy that their greed has produced.
