It's one thing for the Seattle City Council to impose the consequences of its policy on the citizens of Seattle who did not vote for them, it's quite another to impose them on Washingtonians who didn't even have a say in their election.
If the policy works and Seattle's economy either booms or is unaffected while it's citizens all feel better about life in general and their city in particular, the rest of the State is then free to follow its lead.
Returning to those who may suffer the consequences of a policy which they never supported; created by officials for whom they never voted, it kind of sucks to be them.
People tend to worry about the rights of the minority only when they disagree with the opinion of the majority. I doubt all the big fans of this policy have given much thought to those who don't want it, and if they did, most would assume they were cold-hearted bastards who wanted to keep all wealth to themselves.
However this is the way it goes and, in the main, should go. I hope it doesn't get bogged down in endless court challenges. If you don't like the way your city or state is run, try and change it and if you can't, move somewhere where it is more to your liking. It's helpful, in this regard, to remain current on what is going on in your locale and where it likely to go in the future.
This is why federalism with most of the power decentralized is so important. While moving to another city or state is not a simple matter it is manageable and need not be an overwhelming sacrifice. Moving to another country is another matter altogether.
