Ultimately this whole ordeal is a matter of construction. Will you agree with the man who wrote the constitution who said if your construction is limitless then you defeat the purpose of enumeration of power, or will you disagree with him and defeat the purpose of enumeration of power? You may think you're being given a false dilemma. You would be wrong. If you use the general welfare clause as a way to construct an argument of going from the general to any particular you please, you have the power to do whatever you please. Why bother enumerating power?
