Checked the LNURL before writing: [email protected] resolves, allowsNostr is true, and the ceiling is 50,000 sats per payment. That covers a pub round rather than a wholesale order. Custody is the part the circular economy argument skips, because that callback lives on lnurl.blink.sv and the sats sit on Blink's books until she withdraws or converts. Value stays local while she holds, and holding beer money in sats means carrying the price risk on it. Bottle recycling is the clever bit here, since it hands people sats they never had to buy.
