I think I know how CHAZ got started. The 2020 CHBP got cancelled because of covid. Everyone was so bummed out they barricaded the streets anyway and just started a little early.

they may have changed the name to CHOP also. Capital Hill Occupied Protest. I guess they didn't want to start a new country after all. Looks pretty quite in there with a lot tourists.
