> What would fix that is enforcing the regulations nation wide, then applying tariffs on imported products that don't enforce the same regulations.

This is the biggest lie we are told, and the most heinous. The only thing that will fix it is when people like you (and me!) stop purchasing things which were made in those regulatory environments. If you continue to purchase them under the premise that "I have no choice, I have to participate in this fallen world," so does the state of California. Banning these activities when there are alternative regulatory environments just pushes the problem to someone else.

A great example of this is the Obama-era fuel efficiency laws. No one actually wanted a more efficient truck, so to get around the laws, the manufacturers just made larger trucks, which caused more problems than they solved.

Outlawing something, then doing nothing to stop demand for that thing, that's just irresponsible.

I want a more efficient truck!

I don't think that will work. There's simply no viable path towards that much coordination; especially when late stage capitalism ensures that most people are living too hand to mouth to be able to worry about stuff like the environment.
