Yeah, it's definitely not ready. I agree with everything you are saying.
Though, the industry is aware of this and working on it. There is at least one company (Chia Network) where the on-chain language (ChiaLisp) is both capable and secure enough to allow for the sort of management needed to allow for self-custody to happen in a safe, sane manner. GUIs for this sort of thing aren't ready for the general public yet, but are definitely on the way.
