Decentralization and Secession

If a precedent of secession were accepted, then the disintegration of the central government could potentially continue ad infinitum.

The Second Amendment was motivated by much earlier English ideas about decentralizing the power of the king. It was hardly the invention of Southern slave drivers. 

Even if a section of the US were to today secede for some noble reason (i.e., not slavery), the outcome would still likely be invasion and war. 

In a truly free society, the scope of government easily can be reduced to a much smaller domain than even many friends of freedom often think.
