It's true that both cases will get you to parts of the state that are probably more conservative than Salt Lake City, or in Nevada's case, have literally nothing there. But Boulder is about an 8 hour drive from Salt Lake City, and has a dramatically different culture and political climate. If you look at past instances of people fleeing political repression, most of them would be thrilled to be able to drive a day without crossing a national border and live in a completely different situation.

As far as I can tell for similar laws (e.g. age verification), once one state moves ahead on some controversial issue and gets away with it at the Supreme Court level, others follow suit very quickly, and then your odds quickly go to 50:50 when you thought you were picking out the best of 50.
