If you think it's so very important that there be more than one already-installed terrestrial or directional radio broadband provider in the middle of nowhere; you are perfectly welcome to find out what that will tend to cost, and start a charity to subsidize it.
The government can not force private individuals or businesses to provide new services to any random location in the United States that anyone could technically choose to live. That's a good thing, in my view.
As somebody who intends to live further away from urban centers, and knows what distance does to the cost of providing telecommunications services, it is my responsibility to entice others to do business with me, not anyone else's.
If somebody is actively conspiring to prevent new business in this sector, that's one thing; but if the local government, geographic, and economic situation of some place is just such that it's not worth extending ISP services there, that's not in the FTCs purview.
