belief in fiat money (a paper document) can be destroyed in your mind today, if you really want it.

if you absolutely have to get paid in fiat, forward everything to someone else's account and have them send you bitcoin in return. if you need something, send them bitcoin and they'll get whatever you need for fiat.

as for other fiat documents, like identification, passport, registration, licenses - that will take some time to eliminate or reconstruct in your favor, but if you go all into bitcoin, your mind will be freed up to think about those other items more.
