Governments have a legal monopoly on the use of force, and they have the means to employ it. If you can access your bitcoin, and a government can access you, that government can access your bitcoin.
You don't have that option with digital fiat, even if you wanted to.
Yes, you could, you just need to acquire the digital fiat anonymously through one of many methods. Then burn all record of it and watch your money disappear the same way as taking it to the grave, just no death required. Or go ahead and die if you must, but you’ll still not prove that Bitcoin is any different or any less “takeable”.
