You can get away with a dirty contamination bomb and that detonating in down town Manhattan will scare the shit out of millions of people even the ones in New Jersey. Or, you know, just fly a plane into a really tall building and get the state you are attacking itself to get into a hysteria breakdown.

But yeah I agree with you. There is no point in these restrictions except for government bureaucrats to gain power and control over a domain.
