I get that buying your groceries and morning coffee with crypto probably isn't happening anytime soon, but why do you single out those three things? I don't get what you mean by ownership, conversions are automated and easy (things like Uniswap), and transfers are as straightforward as transferring money could possibly be (insert recipient, insert amount, hit send). What do you mean?
Have you tried getting someone from nothing to setup to use all this independently? How long did it take to get them their hardware wallets, multiple backups in multiple secure locations, and various exchange accounts. How much did it cost? Not a chance in hell I’m setting up my parents or grand parents with this crap.
