People probably aren't going to renounce their US citizenship due to higher taxes, but they will move states if taxes in one are significantly lower. This is one of the problems with trying to implement something like universal healthcare on a state by state basis, you need to increase your revenue in order to do so, and the people you most need to tax (the rich) are also the most able to jump ship.

I'd love it if someone could point out if I'm wrong here.

Not everybody moves to the lowest-tax states. There are plenty of people in New York and California, despite the lower taxes in Florida and Texas. People balance costs and benefits, and effective mass transit is definitely an advantage.
