The comparison to Freetown Christinia is thought provoking, but the key difference seems to be that Capital Hill has been a trendy part of town with new apartments going up and rents increasing for the last decade, whereas Christinia was originally an abandoned site.
I don't question the resolve or peaceful intentions of the people currently occupying CHAZ, but instead the patience of property managers, local residents, and local businesses (though closed due to COVID-19).
