Government loyalists can threaten all they like, I have made copies of some of the early versions of the source code just in case they try anything as I'm sure other people have, they will not win.
And what do you intend to do with your backups in case of manipulated bitcoin releases? Start your own blockchain? With a market cap of 0$? For the kids to play with?
You have got that backwards. Even if a
majority of full nodes and miners opt to go with the protocol changes you suggest that is the new branch after the hard fork. The blocks that continue to build on the original blockchain using the orginal protocol supported by clients that use the original protocol supported by miners that still use the original protocol is the
original chain. That is still Bitcoin, even if you attempt to name the new alt coin created by the hard fork "Bitcoin" it is still just another alt coin.
As I suggested it should be called "UnCoin" since the supply would be manipulated and controled by the UN in your ideal scenario.
