I like money as communication of value. On Nostr quite small amounts of currency are being sent but they communicate something more. In services businesses one sets their rate to communicate the quality of their work or to tell the buyer that they shouldn't be tasked with simple stuff or to deal with idiots. Buyers communicate by observing that you get what you pay for, haggling or not.

The massive increase in value of Bitcoin over the years has thrown a wrench into this communication as people may conflate a small gift with the value it eventually obtained. Or depending on how much you think 1 btc = 1 btc, that the value of your time has collapsed versus what it once was. Heavy stuff, so ya know, just have a good time and try not to think about what could've been.
