I agree. I also think we need to consider that it's not sustainable to have a small amount of users pay more just because we don't have more users to zap and consume the content.
Users who can afford to tip more but aren’t because they’re accustomed to getting all their content “free” from ad-supported platforms ought to pay more. The average Nostr user can afford to tip more than 21 sats for good content they consume. Doesn’t mean you have to tip every post or every creator. Doesn’t mean the user base can sustain a living wage. But it means that you, the individual, can tip an actually meaningful amount when you enjoy something.
