Problems in California cause problems across the country, because of their size. If they do this, expect horrible, cascading issues elsewhere.
True so instead, cause them the problems. One reason why gas prices are high is because there are too many standards for the refineries. If they could all just make one formula, it would cut costs
So first step, make a federal mandate on gasoline standards and outlaw states from requiring their own special formulas.
This will create a lot of blow back so as a compromise, allow states that produce more than 50% of their gasoline to set their own standards.
California will refuse and the state will grind to a halt.
Repeat this with electricity. Don't allow them to create their own standards or dictate to the rest of the nation.
Eventually, they will get the hint or their citizens will hang them
