A constitutional amendment make it permanent, but Congress never actually lost control. They always had the power - and still do - amend, restrain, clarify their own laws.

In a scenario with a packed Supreme Court of "yes men" there are no bounds to what could happen, so why bother with the thought experiment? In your example, the constitution is already worthless.
