The big one is if you still work for a company that only has Californian offices that requires you to visit for work. That's the leash a lot of tech workers will find hard to break.
Yes, being a frequent aerocommuter in an income tax state like CA is of limited use, when it comes to avoiding taxes. To me, this is a feature, not a bug. I don't want people causing massive pollution by flying back and forth to the office each week to avoid taxes. It's definitely not something that we should encourage.
