And to give you a slight correction: all ecash is non-custodial (since 1982), it doesn't matter if it's a federation or not. That post was bad.

But I almost don't want to even say it because noobs will take it as "my Bitcoin in an ecash system is non-custodial" which is absolutely wrong. The shitcoin is non-custodial, the Bitcoin is custodial. Always has been.
I totally agree with you on ecash.
Do you think the same applies to Liquid in this regard?
(same that there is no permissionless exit, but the ecosystem of swaps is much more developed)
These definitions need to be cleared up again and again. Ecash is a bearer asset (self-custodial) for itself, but not for the bitcoin it represents.
If a mint gets widely used, but still there is permission and a fee to withdraw to bitcoin it could be priced in (meaning it would worth less than the bitcoin it represents).
