Maybe they attempt this, but with present NY City ‘safety’ collapsing....week by week, and virtually no interest with the remaining police to enforce anything, this simply won’t go too far. Same story in SF, LA, Portland, Philly and Seattle. You’d probably tempt another million odd urban residents to just look for a move to some rural location.
Seattle? Are you kidding?
All they need is the word from Reichsfuhrer Inslee over the Western Washington major TV & radio stations, and Seattle and most of King County would shut down in just half a second. AG Bob ‘Fergy’ Ferguson would happily deploy whatever he has to in order to back up his butt-buddy Inslee.
