The only reason to close state geography data is to protect a few existing monopoly businesses.
Making that data available to the public is a good idea in any case. But the big pro-business reason is that it makes countless businesses possible. Remember the world without GPS? The world with it is better. For countless businesses, as well as ordinary citizens. Geodata should be a rising tide that lifts all boats.
When pro-business means pro-monopoly, something is wrong.
