Run your own mint, backed by your node, it makes it no-custodial.
It will still be custodial for the rest of the mint users, as a single user mint makes no sense in cashu architecture. 🤷
I wanted now to enumerate the benefits of ecash and the possibility of running your own mint, what honestly is equivalent to what you just said, that it improves a lot custodial services, but does not make them no-custodial generally (for everyone). Yeah, I agree.
