This sort of thing happens because as a society we have been trained to become tolerant of all sorts of behaviors. We tolerate people living on public lands because to not be tolerant is politically incorrect. At my winter home in California, I at constantly bombarded by the homeless and every other sort of panhandler whenever I enter or leave a grocery store or a Walmart. The stores even have signs saying they do not promote or endorse these people, yet the laws are now structured so they cannot have them stopped. Apparently, beggars have rights at places of public access.
Everyone can tell the difference between people camping in the woods and people living in the woods. A certain portion of the population just doesn't allow the collective us to "profile" the troublemakers. In my opinion, too much tolerance is just as bad as not enough. I get slammed every time I post that people living in their RVs, not as travelers and tourists, but using them as a permanent home in either RV parks, on public land, or "stealth camping" to live on the streets, is bad for the RV industry. Here is yet another example of what can eventually happen. RVers are but a very small segment of the population. They do not have a loud collective voice. Bad behavior by a small segment of people will eventually lead to laws that throw out the baby with the bath water. As people who enjoy and benefit from the RV industry, we should applaud any effort to end the misbehavior of the few, it will benefit the rest of us in the long run.
