I'm not claiming it is a scaling solution for Monero/Bitcoin though...that's the major difference. I'm giving him an option if he values "instant" transactions more than self-custody (that doesn't make it scale Monero or Bitcoin. The only thing it's scaling is IOUs.)
Yes, maybe I should have expressed myself more accurately. You didn't say it is a scaling solution, but I noticed the same convenient approach of suggesting "just use e-cash" for something, that the coin hasn't solved natively.
Now yes, at least you mentioned, that it comes at the trade-off of self-custody, so I will give you that :D
I don't have any problem with Bitcoiners who are clear that ecash/liquid/custodial lightning/etc aren't scaling solutions for Bitcoin. Calle the creator of Cashu is a great example of someone that is very clear about this.
That is also how I view it.
