How many military families live in Texas? They'd be leaving since the military would be pulled out. The Tejas would have to form it's own military and buy F-16s and Tanks... in order to be secure they would have to tax the people to pay for the military expenditures... Hell removing all fed money, programs and resources would basically do in the Tejas ecomony right out of the gate.
Arguably is right. If they aren't beneficial why do they have them or better, why don't the citizens get rid of them first and then bloviate about secession?This is even presuming that the agencies you cited provide meaningful benefit to a state. Several of those agencies arguably provide nothing of value to any state.
Like I said, just removing the military and building their own security force/military would bankrupt them even if the vote were to pass.As for the Texas economy cratering because of a mass exodus of people.....if secession were to occur today, that is likely to be the case: 75% of Texans are opposed to secession. Should that percentage ever turn in favor of secession, that argument necessarily becomes suspect because the mass exodus in question becomes unlikely--people aren't going to vote to secede from the US then rush to move to the US.
