Let's just suppose for a moment that is all true, the end of the world is nigh. That's not up to the court to decide. The court exists to determine the law. The Constitution is not just a list of suggestions, it is a legal contract and the job of the count it to insure that the terms of the contract are followed. It's simple. Congress cannot cede it's authority to make the equivalent of law to a bunch of appointed, not elected, bureaucrats, even if there is a possibility that the proposed regulation is in fact correct. Being right does not give you permission to violate the terms of the contract when you are specifically not allowed to pursue that action.
It's the same as Roe v Wade. It matters not if you think abortion should be legal. It matters is what is in the contract. Even Ginsburg thought the Roe decision was badly written and subject to reversal. In the 50 years since, knowing this was a potential problem, it could have been explicitly grounded via a constitutional amendment. No someone in charge actually reads the contract and correctly explains that this is really not covered. Not like you did not know this was a possibility. Want the contract fixed, go through the process and amend the contract. That's how it works.
