If it were up to me I'd make the US into ~100 states and reverse a lot of the power transfer from the states to the feds that's happened over the past 100yr.
In the grand scheme of things brexit might be a bad idea, but you're effectively saying people shouldn't govern themselves because they would vote for more self-governance...
That's how decision making power should reign.
It's nothing short of a miracle that for the past 150-200 years, we've managed to fill much of the world's power space with a system that roughly serves the people (with lots of flaws, but nevertheless). Let's hope it isn't just an anomaly.
Then let that power vacuum be filled on the state and local level.
West Virginia and California should be free to run their societies into the ground (or not) in their own ways without the other telling them how to do it or being on the hook for the cost.
Don't straw-man me, I'm not saying we should dissolve the federal government. I'm saying states need to be less under its thumb and with that comes some responsibility for the consequences of mismanagement. Some of those consequences compound (screw up your state enough and all the people who can move will, taking their tax revenue with them) but that risk seems like a pretty low price to pay for more government happening on a level that is easier for the average Joe to influence.
If they can somehow reconcile your eye color restrictions with existing state law, the US constitution, etc then sure, why not.
