OK so this blocks the likely mechanism they would use for the climate agenda, but it also sets a precedent that could be used to limit the power of other agencies. In an ideal scenario, this leads to the dismantling of entire agencies like the department of education, the centre for disease control, the food and drug administration, the drug enforcement agency...there's more of course...

If Congress is not allowed to delegate these powers to the EPA, then by analogy they should not be able to delegate the power to mint currency to the Federal Reserve.
