My real opinion is that no one is more trustworthy than the other. They're all people. But there are constitutionally delegated duties given to each branch that we've gradually eased over the past century, and between Jarkesy disallowing in-house courts for certain types of crime, the resurgence of the non-delegation doctrine and now the overruling of Chevron, SCOTUS thinks this delegation is not optional. I personally agree with them hesitantly, but predicting the future is hard, and there are some actions they take where I think the consequences are obvious, but this is not one of them, and I would have slept no more or less soundly if this case had come out the other way.
