You're paying not only for us to host the infrastructure and process payments, but to hold the payments up to 24 hours; there's a real cost to keeping those sats in transit and using an HTLC slot on our channel.

Sounds like you want to be the new banker, taking cuts from everyone.
Nothing stops you from hosting your own infrastructure.
Zeus offers an easy on-ramp.
I would never use Zeus!
I see that you use a custodial wallet. Why wouldn't you use a non-custodial wallet like Zeus? Why would you prefer to give your Bitcoin to total strangers, rather than keep it safe yourself, in your custody?
I'm really keen to find out why you think giving your Bitcoin to total strangers is better than keeping your Bitcoin in your own possession. 😂
