I don't think it's ambitious, I think it's retarded! Even IF I was able to earn that kind of money posting on Nostr I wouldn't want to! My posts aren't that valuable and Nostr isn't pleasant and useful enough for it to be worth it for so many people to use it, let alone PAY to use it!
That kind of reasoning doesn't demonstrate responsibility and accountability. If Nostr produces any kind of possible value outside of sats then the people shilling for it should be willing to drink their own cool-aid and shouldn't need to be reimbursed for their presence.
