Gabu from a legal perspective, before government decides whether it should do something or not it should first determine whether it has the constitutional authority to do so. If it doesn't have the authority then it shouldn't do it.
Now if you want it to be a philosophical discussion as to the proper role of government then I think the constitution does a pretty good job of it. So for me the legal question and the philosophical question are pretty much the same. My only real exception to that is that I would prefer to limit government even more by repealing the 16th amendment.
But this isn't a legal question. It's a philosophical one, asking what place one thinks that government should have. If you agree with what the Constitution says, fine, but state why. Just quoting the Constitution and saying "case closed" does not help the debate along at all.
