Yes, this exactly. The goal is to never have to eventually never have to go back into fiat for all the reasons everyone understands well - inflation, censorship etc.
If you already invested in early years, got fortune and your financial status now is like financial free, you will never return to fiat system that is very understandable.
For new investors, who are still practicing with investment, storage and waiting for profit, their complete exit from fiat system will need time like several more years, some more market cycles. I believe that senior Bitcoin investors with good profit from their investments will not want to return to fiat system that is controlled by governments and central banks.
Governments and banks can seize your money in bank accounts but they can not seize your bitcoin in your non custodial wallets if you don't do any illegal things.
