One day, they'll probably accept bitcoin without even realizing it. Probably so. It's like using a car to get from point A to point B—you don't need a full understanding of how the engine is built.
But! For the next few years at least, I'd prefer to see more aware merchants. Not the kind who just get fiat on their end while I'm paying in sats, but those who actually understand the value of what I'm sending and treat it with care.
I also don't think it's such a "pain"; some systems make it pretty smooth for the business. The real problem probably lies in there still not being enough people paying in BTC, especially in the western hemisphere.
