answer:If the Constitution says we must have a postal service, you can’t sit here and question whether or not that’s still valid. Because if you did, then everything in the Constitution becomes questionable and then everything in the Declaration of Independence would be questionable as well… and if enough idiots decided to dismantle the postal service, before you know it, there would be no free speech except what the Republicans deem appropriate, people of German descent would be forced to stand trial for the Holocaust, and probably not long after that, there would be a “national religion” enforced by the insane right wings who insist that everyone not of their religious beliefs are going straight to hell tomorrow. Not a good idea.
