Ya, i think the nature of ecash on top of lightning brings back some of the qualities of btc layer 1 that i miss when using lightning. Such as it being sendable and receivable off line. That coupled with the privacy gains and scalability seems like a far superior tool for something like zaps.
I think for me im realizing the dream of everyone running their own lightning node is never gonna happen...so if the alternative is custodial lightning...then we need ecash so that custodians are blind to linking users with transactions. Then we need fedimints with ecash to disperse guardians of the ecash mintsso less rug risk.
