It's a slippery slope. Yes, Texas doesn't have state income tax but we do have the 6th highest property tax rate for example. Income tax is just 1 component of how states make money. It's a little short sighted to just look at income tax. As others have stated, this doesn't even take into account cost of living and local taxes. I really don't think implementing something like this is going to all of a sudden make all the good FA's flock to teams in income tax holding states.
