Even if Congress did so delegate, Congress does not have the power to delegate textually committed powers any more than it has the power to delegate the power to make laws in the President.

Yeah? What do you call the regulatory powers delegated to Federal agencies?

this issue isn’t even up for debate.

How Goresque of you. Declare the issue undebatable, by authority of your "earlier posts".

[Publius Valerius]

Well, gee, I guess when a power is textually committed to one brach of government and the Supreme Court has so held—without objection—multiple times, I imagine that to most thinking folks, that would close the debate.

Federal agencies only have rule-making authority, not legislative authority. The Supreme Court, rightly or wrongly, has drawn a clear distinction between the two.
