If you're "doing business" in the United States, you're subject to those laws. This is just how it works.
If you're sued and you don't defend yourself, you will probably lose by default, so you can have a judgement enforced against you. This might preclude you from travelling in to or even through the United States.
If that last part is the only thing they can do, I say move to somewhere warm and cheap and just "agree" to their terms ;) I thought they could call InterPol on you or something...
