Housing is too expensive for many people in many places. The normal healthy response to housing being too expensive in an area is to live in another area. Only a very small minority of people who can't afford housing in a place they'd like to live respond by becoming homeless in that place. It's simply not a rational response to housing being too expensive.

It's not easy to leave your social network, job, and home to look for better opportunities while living hand to mouth. Things happen unexpectedly.

And it's not particularly insightful to point out that people who are homeless often have difficulties coping with the demands and challenges of life.
