Plus:
1. California "country" would have to solve its own enormous debt problem, with no help from the U.S.
2. California "country" would have to negotiate trans-national-boundary water rights from the U.S.
3. The gigantic flow of entitlements from DC to California "country" would stop.
4. California "country" would still have to deal with the staggering illegal alien problem (that it currently won't acknowledge exists).
Oh yeah, California's gonna secede. /sarcasm
