The rise of this lifestyle is a direct result of rising inequality in our society. Yeah, that mother of 2 living in a vehicle probably has way bigger problems than paying for disposal service. But people utilizing services they can't pay for is what concerns you, not the fact that so many people are in such dire financial straits that living in a car makes economic sense.
Use of the word "NIMBY", which is clearly a pejorative, is not an argument. I don't see why that diminishes the parent comment at all.
The rise of this lifestyle is a direct result of people feeling entitled. Take the musician in the article ("Lily"). She's trying to make a career in indie rock, playing local gigs. That can't be your full-time job unless you are exceptionally talented, to a degree where others value your creation/contributions enough to pay you a lot for it. This takes more than just musical talent - it requires experience, marketing, networking, business, and other skills. And it is of course, a highly-competitive line of work - after all, who wouldn't want their work to also be their passion.
Lily lived in Nashville before, which is a lot more affordable than California cities like San Diego, Los Angeles, San Francisco, etc. San Diego is a full 55% pricier than Nashville (https://www.bankrate.com/calculators/savings/moving-cost-of-...). So in effect, Lily made a conscious choice to move to a pricier area without having a plan for how to live there. A responsible way of making that move would be to work for a few years in Nashville, build up savings, identify jobs in your destination that pay enough, and then make the move.
What gives Lily the right to expect she'd be accommodated in whatever city she moves to? If her work is not producing enough earning to pay for housing locally, it is because her work is not valued by society to a great enough extent to live in a very desirable (and thus expensive) area. I don't think the local community is obligated to provide lower-cost housing (either through subsidy or greater supply) to enable her choices, which squarely fall under the realm of "personal responsibility".
