At a traditional bank you have your national deposit insurance scheme; you get that in return for converting your "assets" to the said nations issued currency but accept the authorities control of the money supply and your funds.
With decentralised money, you get the safety of a globally distributed attestation backed by cryptography without a single authority controlling the supply of money or your funds.
There is no halfway option. You either have a single authority that can exercise control or you do not; number of delegates for exercise of control is almost irrelevant since you can change banks.
I mean you're just making bare assertions, of course there are halfway options. Different components of the account or relationship can have different parameters. Most crypto products are not the equivalent of depositor accounts anyway, they wouldn't be insured necessarily at a traditional bank either.
