Sure, there are all kinds of people in the world, but would that group represent more or leas than 1% of users?

You wouldn't know how much demand there could be till you build it, iterate and innovate. You can't ever do that if regulations stifle it completely.

I don't care. But I'd rather live in a world where tinkerers can tinker away since I imagine they'll be able to make something I would care about later as a consumer.

My best guess is probably goint to be more than 1% in markets where SMS is commonly used. Not by much, but more than 1%. Maybe 2-3% tops.
