This worked for GPS [0] because it was conceived as a purely military project (and still is mostly). Once established, it was opened up to civilian and commercial uses. But even so, other countries and supra-national organizations decided they needed their own navigation satellite systems, and now we have Galileo [1] and Beidou [2].
Maybe if the military had done this first, a similar path would follow (not likely though). As it is, the military is planning their own massive LEO satellite system [3].
