Which would be great. These agencies and bureaus have grown to an enormous scope, completely without the consent of the governed. Doesn't sound like a republic to me.
It would be catastrophic, because Congress as it stands is utterly incapable of legislating. This is why the little stuff gets delegated to unilateral decision-making withing the executive branch: If making new rules was left to congress, they could never keep up. The world moves fast, congress moves slow.
Instead, they delegate powers to agencies that can make rules within some tight purview and pursuant to some defined purpose, and if they step out of line Congress is completely within their power to legislate their preferred stance into law.
