Give an example to me of something that is unspecified or not a violation of the Constitution that is unconstitutional then.
One example I can think of is the Noise Control Act of 1972, which puts federal regulations on noise pollution. Nowhere in the Constitution is Congress given the delegated power to regulate noise pollution, unless of course you use a silly interpretation of the General Welfare Clause or the Commerce Clause. Pretty much anything the U.S. government does that is not justified by a delegated power is unconstitutional.
Notice that the Tenth Amendment says that all powers not delegated to the federal government are reserved for the states. Pretty much pokes a hole in the ludicrous argument that the federal government is free to do what it wants as long as it doesn't violate any part of the Constitution.Was noise pollution an issue when the Constitution was written?
