Still, it would be pretty inconvenient if newegg, amazon, other online stores wouldn't ship to your home address. Netflix, other services could block them based on billing address. Yes there are ways around this, and the real issue is patent law in the first place. Just a thought experiment.

You hit on a more important point: the real issue is the patent law. In East Texas there's a certain ideological slant, and it sucks for legitimate companies. But in the end, they're merely implementing the law. Pretty sure punishing a municipality because of verdicts in a federal court there would result in a fist in the mouth from the FTC. Marshall, Texas, or Boston, or San Francisco, or wherever, results in zero change - the real effort needs to take place in Washington DC.
