That's a good way to lose 50% of your revenue overnight, not to mention be involved in hefty lawsuits (with governments no less, let alone corporations), and to instantly lose your claim to being an international institution.
You think that if they did that, the EU wouldn't be able to set up a bunch of rootservers overnight, inform all their registrars that they were the definitive rootservers for the EU domains now, and then ICANN wouldn't be forced to offload all queries for .uk, .eu, .fr etc. to those servers in order to restore connectivity?
People forget just how large a market the EU is. In many cases it generates American companies more revenue than the continent of America itself.
