imo “censorship resistance” is pretty much the only real use it has, i.e. generally for things outside of or on the edges of the law, such as drug marketplaces or transferring to and from sanctioned countries

with that though, while it does have some technological benefits to achieve that, imo the main reason it’s been good at it is that the space had been kind of ignored by regulators for a long time, and these things have been getting steadily more difficult. Like with exchanges in the EU/US now requiring you to identify yourself etc, it’s more difficult to actually get money in and out of the ecosystem anonymously
