It's not a housing problem, it's a drug and mental health problem. Many of the unhoused people you see could stay in shelters but don't--often the areas near shelters have the most camps near them. They simply don't want to follow any rules and now conditions are so accommodating that being outside in good weather is better than staying in a shelter with a curfew.

Shelters are not widely known for being safe and accommodating places.

Most people would chose camping over them.
