More importantly, it is now clear that American States can tax non-residents, even FOREIGN non-residents who have no connection with the U.S. whatsoever. There will be collateral consequences to this decision. For example, why should I have to pay out-of-state university tuition if I became a state taxpayer due to the sales--and soon to come other--taxes? Drive a car into my state? You have to pay a roads tax. It will be interesting to see how far this goes. Long-arm jurisdiction will become more robust, at the least; another rationale for diversity jurisdiction is removed.

>>For example, why should I have to pay out-of-state university tuition if I became a state taxpayer due to the sales--and soon to come other--taxes?

Did you pay income tax in the state, which will be what supports the university? Congrats, you get in-state tuition.

>>Drive a car into my state? You have to pay a roads tax.

Two points: 1) you are using the roads in the state, why can't you fund them? 2) that tax already exists, you pay it when you buy gas.
