i’m curious what counts as “dystopia level of financial surveillance,” these days… recently i made a cash withdrawal from my personal account ahead of a trip abroad (they asked me why) and within days received a FinCEN notice in the mail warning me about “ structured transactions”… having made no other cash transactions days or even check cashing or writing days before or days after.
