There are different kinds of homeless people.

Some of them might do well in such a setting.

But more than a few of them would be disruptive and ruin the land and ruin it for everyone else.

There are plenty of articles and videos about what ends up happening to these encampments- they turn into dumps with piles of used needles and lots of human waste. The last thing you'd want is something catching fire and spreading.

Generally, most habitable 'live off the land' type of places are spoken for already, no nearby property owners are going to approve of such a 'zone'.
