No, that cuts the other way. The only reason we allow the FTC to create regulations with the force of law is by pretending that regulations are just an expression of how the executive will exercise its delegated discretion in enforcing the law. That makes rulemaking a quintessential “executive power.”

Your argument amounts to the idea that, because Congress has done one wrong thing (allow the executive branch to make laws) it should be permitted to do a second wrong thing (allow the Article I “executive power” to be exercised independently of the President). That makes no sense. You can’t reward Congress for doing an unconstitutional thing by letting them do a second unconstitutional thing.
