Lets do a hypothetical:
"Is X law in violation of the constitution if they regulate Y"
Regardless of X and Y you could argue the federal government is acting outside the constitution.
In practice I think there do need to be regulations above state level. I think some problems are legitimately difficult to control at the state level. But is that outside the founders intention? Perhaps.
Recall explicitly that interstate commerce is a federal authority; there are lots of regulations within that pervue.

And they use Interstate Commerce to regulate things they have no business doing.
19 enumerated powers. Everything else to the states or the people.
