You always need a 3rd party for two individuals to transact. It's banks for dollars, miners + the whole infrastructure for crypto.
In principle, miners or the infrastructure maintainers could be forced to never mine your transactions (well, transactions to/from particular wallet IDs), by the way. It would be of course harder, since your money is in a single bank, but all miners would have to agree to the ban for it to work.
Smaller jump then gold -> usd -> btc which actually means changing the global reserve currency.
If you think about it didn't the U.S. government did a similar thing by gold. USD was pegged to gold initially, then they changed it.
