I don’t think an originalist would take this view. To use hyperbole, I don’t think anyone intended the bill to empower the epa to shut down the energy industry.
The bill is clearly not intended to “shut down” anything. It empowers the EPA to protect the quality of the air that we all breathe, and that’s how it was applied. If coal power plants need to externalize their pollution to be financially viable, that says more about our failures to preempt the situation than some kind of bloodthirsty plot on the EPA’s part.
