I have two issues.
The first one is fundamental: I do not believe BTC should be used as currency *just yet*, and even when it plateaus and its fiat price volatility is similar to that of gold, I will probably still think the same. It's just too valuable as a store of value. To me paying in BTC is akin to paying in land or gold. Absurd.
That said, if we *have to* use it for small payments, I think the whole concept of Lightning with its channels should be made analogous to topping up a debit card, or a prepaid phone card, or something like that.
Many people are used to operating like that, so "just" (I know...) target them.
I'm not one of them, and I thoroughly hate the concept of having to top up, but that doesn't mean anything.
