have you looked at people's LUD16s? almost everybody and their mother are on custodial zappers, even people that run LN nodes.

Cashu is strictly an improvement over CUSTODIAL lightning.

And since it uses lightning, you can just continue zapping without ever running a mint or having a sat under custody, the only difference for you will be that instead of paying a bolt11 of wallet of satoshi or strike you'll pay a bolt11 of one of hundreds/thousands of mints.
