Soft secession?

[BrianSoddingBoru4]

States seceding from the Union has become a popular talking point in recent years.  Republicans speak of a "National Divorce" in which the red states secede and become Republican rule.  It has been noted that blue states are net positive in that they pay in more to the federal government than they receive in services from the federal government, whereas red states are often net negative.  The idea of a soft secession in which the blue states simply stop paying to the federal government, since they have the money to replace the services provided by the federal government.  Pakman talks about some of the complications, but what do you think?  Is this doable?  If it's doable, is it advisable?

It’s illegal, which kind of makes ‘doable’ and ‘advisable’ moot.
