Lots of ‘legal ramifications’ to be dealt with.
Some open questions:
What happens to US military installations in TX? Who pays for them? Do they stay and belong to TX - with or without the ‘contents’? Does TX create its own military, or could it/should it ‘pay for protection’ and let the rest of the US provide the military?
What happens to Texas taxpayers who paid into social security and medicare? Do they keep paying in and then can draw out? Do they lose the right to to draw out?
What about retired federal government workers or retired military in TX - do they continue drawing their pensions? Do they now escape paying US federal taxes on the pensions?
The US debt is about $20 Trillion. What portion of that debt belongs to TX and its citizens?
Look...seceding from the US SOUNDS nice...but there are LOTS more questions....in search of answers.
For the BREXIT...there is a 2 year transition period to address some other their possible problems. How many years would it take to provide a proper ‘separation and divorce’??
Your questions are cute ... I didn’t forget /s did you?
Anything that is not an earned benefit from the foreign nation USA, would be lost. If people want their SS, Medicare, Medicaid etc, they are at the whim of that government. I am not a young man anymore, and I would give up any claim to perceived benefits, to live and die in a free land. The US debt, is owed to a private for profit corporation, the “Federal Reserve inc”. It can be written off with a stroke of the pen and a shout of Hi YO Silver AWAY...
I think of it like a corporation that divests its best company so as to keep the rest of the corporation solvent. Texas will run economic circles around the rest of the U.S. if allowed to be deshackled from Washington and allowed to grow their own economy.
For one thing, when Obamacare enslaves every American citizen under single payer, a free Texas will be where the rich and connected will go to avoid the long lines and poor services that comes with “free” health care. Texas will be for the U.S. what the U.S. once was to Canada, only moreso.
In short, Texas will buy their way into paying off the army bases, air traffic control system and other federal entanglements in order to nationalize them and they will set up a system to honor our veterans and social security recipients. There will be (at least at first) an income tax to help pay for all the new services and security Texas will need but it can be done.
For liberals, they subtract two conservative Senate seats from Washington and more GOP house seats than Democrats so there is an upside for them.
For conservatives, there will still be one bastion of liberty and freedom after the U.S. becomes a completely socialist state.
None of the issues you raised even holds a candle to gaining independence. You are using socialism to uphold the status quo which is - socialism.
