It feels like the endgame for LN is for all transactions to stay on there and never actually settle on the actual block chain which is basically just making everyone use a less secure, more centralized bitcoin (akin to the normal banking system). LN has no proof of work afak and there is no "full transaction list" being distributed to all the users. it has the same "problems" that nostr has with missing posts/followers and spam but the problems actually matter since it's for a medium of exchange instead of dumb microblogs
