If the point of an MVP is to reduce product risk (and I think it is), then yes, products where you're essentially certain that if you build it they will come don't gain anything from an MVP -- you've already solved the problem it addresses. The people who are beating the drum for "always do an MVP" suspect that founders systematically overestimate how well they've figured out the market and how exactly they've nailed what their customers will want. I think they might be right, there's a "whistling past the graveyard" habit that optimistic startup-types take on where they avoid bad news in the hope it'll go away.
