Lightning tradeoff is much more than just liveness, it's capital requirement. That can not scale to average people making small transactions daily without centralization. Which is exactly what we see in lightning. Tell me, how many people on nostr are self hosting their lightning node and getting zaps to it? This is the most hardcore bunch there is. They're not doing it. Because lightning is far too expensive in time and money. You can make the learning time go away with enough UI improvement, you cannot make the expense go away.
