Feel free to use. The solution is not banning camping, but, rather, providing a safe, legal campground with sanitary facilities.
Camping is an imperfect solution, but is absolutely necessary until housing can be had by all.
Criminalizing people looking for housing adds to people's criminal records, thus complicating their ability to regain housing. I invite you to visit us at street roots where homeless and very low-income people have come together to create a community where we work to create our own solutions. We have found a voice and a place to regain our personal power and hopes. I wouldn't make a law that says you are a criminal if you sleep in the only bed you have.
