This whole camping trend, whether on beaches or in parks or on other public property, makes no sense to me. Society is built on the expectation of protected property (reserved for certain uses), enforcement of laws (such as litter laws), and earning of privileges (rather than feeling entitled to live wherever one wants). I don't think it is fair that law-abiding residents who pay taxes and have worked to earn those pricey homes can have their public amenities, which are meant for day-use, instead crowded-up by transient residents. It just defies common sense.
In Seattle, we see the effects of similar permissive laws all around us. Property crime has gone up significantly alongside our recent lax enforcement of littering laws and due to the allowance of "urban camping". We have induced a large homeless population from elsewhere due to our permissiveness - even from cities immediately next door (https://q13fox.com/2019/02/26/did-federal-way-bus-its-homele...). The rise of RVs taking up parking spaces is another problem - it is essentially freeloading off of spaces meant for use by residents of that neighborhood and for temporary day-use. And of course, these RVs are a blight - they are often in shoddy condition, they make the neighborhood look less safe, and they leave trash all around them (or worse, sewage runoff). Many have needles around them and are clearly used to deal drugs. With burglaries happening often, I can't tell you how anxiety-inducing it can be to have someone pitch a tent on the sidewalk in front of your home, camping there all day everyday, watching all residents' movements, etc. This city used to be beautiful and it is trended towards a trashy Mad Max like situation.
I don't agree with arguments that this is due to cost of housing or supply issues. This is due to people feeling entitled. If one can't afford to live in some area, then they should consider finding a different area to live in, or a different line of work that enables them to live in that area. No one is entitled to live wherever they want, doing whatever job they want (e.g. the musician quoted in the article), at whatever wages they are able to earn in that job. That's simply not tenable. There are plenty of affordable places in America where people can make a living and thrive. And yes, it may require that you look outside of the most-desirable locations, or that you do work that isn't your "passion", but that type of compromise is simply a part of life.
