It's funny how regionalism pops up on the internet. Thing is, it's less than 10% of the country (and surely not all of those 29MM are on the internet), and there are other businesses surviving just fine foregoing a TAM of the whole country.
It's not that Texas is inconsequential. It's that the choice is "cut off Texas or risk the entire business in the other 49 states".
And because HN only allows me like 3 comments a day, I'd like to emphasize "can."
