You might be thinking about the taxes. The government doesn't tax itself. For example, the post office is exempt from paying federal taxes. So that makes the business model you are exploring even better. Higher quality and lower cost should be the result. Throw in a federally enforced monopoly and now your are talking about a massive innovation impetus on top of everything else. It's a no-lose situation.
It's easier to run for office by telling the majority of people that we won't tax YOU but we will take money from those other people over there and give it to you or otherwise make them pay for government services so you won't have to. If you vote for me.
