It's not that there's no need, it's that there is no way. Or did you miss the memo Lincoln sent out?
The need is great and if I thought that there was any chance in hell, I'd move my family to whatever state was planning to do it *if* they had their stuff together.
Problems:
1. Military. Your second amendment rights mean a pile of nothing right now. State Militias have been absorbed into the Federal Government. So, what, you're going to pick up the 30-06, Dragunov, or Barret .50 and fight an F-18 squadron? Yeah. This isn't muskets and cannons anymore, folks.
2. Economics. The Federal Government has it's claws so deep in our local economies that it's nigh on impossible to operate without their money which, of course, you don't get if you don't play by the rules.
3. Infrastructure. Tie this in with economics. If you cede, you damn well better have a plan to provide things that people in this day and age won't live without. 911, police, etc... What about local agencies that will be required to oversee trade with the Federalist states. Imports, exports, blah blah.
4. Motivation. I'm motivated, are you? I believe you are. What about the bulk of constituents in your state? It seems to me that it would be harder to convince constituency to cede than to affect change in the established system. Both options at this point seem so terribly remote that I'm very discouraged.
There's more, I'm sure. Thoughts? I'm a pissed off citizen that has been thinking of this very subject for a while now, it just seems impossible and it's certainly discouraging especially when you try to talk to folks in your area about it and are met with the ingrained brainwash.
