Why would somebody pay for a meeting. They either are invited or not. Otherwise it is almost like people should pay you in order to talk to you.

I used to bill my clients $300/hr. And they are happy to pay for the expertise.

Yes, but those are already invited right? If you don't invite them you wont get money, if you do, you will get money. So nothing changes right?
Not always. But yes, there must be an agreement somewhere that they agree to that rate. And that agreement can also be on nostr.
That only works if you can enforce it. So if the zap is never paid, what advantage gives it over the usualethods that you use to let them pay?
