It's an attitude I've encountered with some Californians. I wouldn't call it a common one, since most Californians seem to be aware of their dependence on their neighbors for energy and water. But as for "kicking out" California, I'm not sure any such mechanism even exists in the Constitution. While the USA might not be a proper federation of states anymore, vestigial bits of the federation still exist, particularly when it comes to representation and self determination of states.
If a civil war or rebellion did break out I don't think it'd happen along state lines. The kind of power the states now wield actually depends on the existence of the union, so I don't see them wanting to destroy that relationship.
