my vision approximately is that a node puts an order in with a peer in a nostr-based marketplace where reputation can be factor

A service fee goes to the coordinating peer who adds you to a round, rounds execute based on any number of preferences

So nodes willing to wait days for a channel may get them nearly free as they're subsidized by larger and high time preference ones

Most nodes will only ever have private low-moderate volume channels so they should last easily as long as a car or any other major household appliance

As for closures there's always "room", at what price is the question... undoubtedly closures will cost more than opens but that's also optimal from an incentives perspective

If people are going to accept some trust with shitcoins and federated hoaxes, queuing for a batch channel open is a no-brainer
