You are seriously misinformed on CHOP/CHAZ. Likely 1-5% of the area was devoted to a garden. The rest was filled with protesters waging nightly war on the police and surrounding businesses. More than that, CHAZ/CHOP protestors were directly responsible for multiple killings of black people.
It was not mostly centered around urban farms. That was only a tiny, tiny slice of Cal Anderson park. It wasn’t an actual farm either, but desperate PR - they threw down a few bags of soil a few inches deep, and obviously nothing came of it (in terms of food production). I am not sure the size of CHAZ even matters - it was a chokehold on the most frequented parts of Capitol Hill, the businesses in and near it, and the roads used by tens of thousands daily that run through it.
As for how safe it was - it was a lawless zone that gave safe harbor to crimes (including murder) and weapon stashes used by BLM/antifa affiliated rioters to attack the nearby police precinct. Here are some sources:
