I don’t believe that Cashu should or can replace non-custodial Lightning at all. There are use cases in which Lightning just doesn’t work, Cashu can fill these gaps.
Comparing this to shitcoins is ridiculous though.

i don’t see why its ridiculous. If it works on cashu but there is no liquidity from the cashu node to anywhere else on lightning, this is no different than a shitcoin. Its worse then a shitcoin, its just a token you can’t use for anything.
Without the promise of eventually getting bitcoin out of the node via lightning, it’s just a valueless entry in a database.
Yes, that is correct. All of the above is true for any custodial system, no matter if Cashu, Lightning or On-Chain. From those three Cashu offers the best tradeoff imho.
However the comparison you make is too simplistic. Cashu is custodial, there is some level in trust involved. The trust is not in the system, it is in the mint. You can move between mints or use many of them. You can use the mint of someone you know personally.
There is a lot of nuance in this.
😳👀🙄
Cashu is nice, but it needs the underlying fulfilling layer.
So OPs expectation creates paper bitcoin, that you trust you can redeem later, because now you may not have liquidity for that.
