The friends and family route works the first time around. You couch surf until you find a job, as you go through your contact list people are happy to host at first, but there comes the awkward "so... it's been a couple weeks... how's that job search going?". Then you have to put your job search on pause until you find a new place to live.

Eventually your job search keeps turning up "no" because they don't like the answers to "can you explain this gap on your resume?" and they really don't like the answer to "do you have a permanent residence" or "do you have any drug-related convictions?"

Hopefully you find a job before you've exhausted the good will of all your friends. And pray to GOD it doesn't happen again because the next time around, each one will have an excuse as to why they can't host you. "Oh sorry, we've got our inlaws, try X, Y, Z"... who are also "unable" to host.

So then your car is your home. If you're lucky enough to have one. But the point is "just have friends" isn't a solution.
