I'd put it even stronger: we need use cases that can only be achieved by using bitcoin. Cross border payments (I did some work for people based in Portugal and we settled in bitcoin which was delightfully easy) might fit the bill. But that's not even quite what I mean.

Maybe it looks like in-game money for gamers or tipping and payments for adult industry or marijuana industry people. People will gravitate to Bitcoin when they have to, when it's the only way to do something they really want to do.

This is one of the reasons I like SN so much. It's a thing that can't really be achieved with anything else (I suppose we could all buy CCs with credit cards and then shuffle them around and withdraw back to some banking app or something, but I think it would be way more clunky than lightning and probably illegal unless kyc'd and regulated).
