Something I seem to be having difficulty explaining to you, or you simply don’t want to understand it.
Congress is you.
All power is given to congress by you.
The 10th amendment does not restrict Congress from making law, or creating agencies to enforce it. Ceding responsibility is also in their ability to do, either through action or inaction.
If the 10th restricted Congress in the way you apparently think it does, then congress would be no more than a social club, with a bar. “how ya doin Ohio!, fine said Nebraska, How’s the kids...”
In other words, they would be useless...
Congress is you.
All power is given to congress by you.
Bullshit.
All the power that Congress has was given to it by the States and codified in the US Constitution. Unless and until it is modified by amendment, those powers remain as they were originally understood and intended by those who wrote and ratified it. None of us have to power to alter that except by the process of amendment.
In other words, they would be useless...
No, they would have the explicitly enumerated powers, e.g., coin money, and raise and support armies.
You should read the Constitution some time.
