housing *always* goes up. There are more people tomorrow than there were yesterday, so demand is going up, but there's no new land.
Why on earth should the federal taxes of someone making $80k in Tennessee subsidize the housing of someone making $80k in SF?
They shouldn't. The net flow of funding is from CA to TN, not the other way around. Nit picking the details is political, not economic.
The GPL's negative effect on freedom
Nope. The government stepping in and putting you in jail for lynching undesireables is a "negative effect on freedom" but is still a net gain in freedom. "Forcing" freedom is still more freedom than anarchy. In practice, anarchy quickly becomes a warlord system. So GPL, forcing those who use it to remain open isn't a negative effect on freedom.
Unless you think that putting a mass murderer in prison is a negative effect on freedom.
