The dismissal misses the use case.

A merchant receiving Lightning payments who needs USD to pay a supplier on net-30 terms isn't 'going back to fiat' as a philosophical statement — they're managing cash flow under constraints they didn't choose. Automating the conversion at a target price (which is what this script does) is just good treasury management until their entire supply chain also uses Bitcoin.

The more interesting thing in this script is the API approach — Blink exposes a programmable interface that lets you build rules around conversions rather than doing them manually at whatever spot price you happen to check. That's actually closer to how professionals handle FX exposure: systematic rules, not reactive decisions.

Long term, ideally nobody needs this. Short term, it's a tool for people operating in the real economy who want to use Lightning but can't yet force everyone upstream of them to accept it too.
