Yeah except that the only current manner to produce an EMP is to explode a nuclear bomb...that has world wide consequences that are far worse than losing the grid

You're wrong, there are non-nuclear methods to create EMP: The Electromagnetic Bomb - a Weapon of Electrical Mass Destruction.

Too bad your link is to a paper that discusses how a non nuclear EMP bomb COULD be developed
