most of his arguments are pretty shallow and dissolve when investigated deeper. I wanted to give the pod a listen anyway to see, then the first half he describes a system using nostr to RPC a LN node so someone else can run the LN node for you. WHICH IS THE SAME TRUST ASSUMPTION WITH ECASH. You're trusting that someone else doesn't rug you, so 1. don't use it for large amounts or 2. only use it with someone you trust deeply. just like a cashu mint or fedimint. The rug risk or the risk of banks using his model is just the same, except 1. you don't get the privacy of ecash and 2. you get 0 offline capabilities. You might be able to get some fun things with signatures (like p2pkh in NUT11) since it uses nostr but seems very limited otherwise.
