Ah hah, you've definitely found a good itch to scratch there.
I can see what you're doing as being useful for a whole bunch of things once the parties involved are all satted-up, super interesting. Commissioning creators comes to mind.
As for getting satted up in the first place, I'm with you on the risk element.
Part of me thinks Primal’s solution, by means of which new users are essentially buying pre-paid zaps via Apple or Google, is the only on-ramp that won’t have an egregious drop-off rate. Like I was the head of Nostr marketing and growing the zap economy was my main KPI then I'd channel all new users to Primal. What they've got there seems to be fully-compliant, fast and clean. Single point of entry to the zap economy isn't so robust though.
