Yes, very ideological. Some people want government to run like a business. Is your state/county/city not profitable enough? Then your state gets fired or downsized. Or maybe sold to the highest bidder.
In any event, the US Constitution requires a post office.
US Constitution, Article 1, Section 8
> The Congress shall have Power ...

Not that I think they should, but Congress could legally vote to abolish the postal service. They had the power to create it but they weren't required to.
I think my state has already been sold to the highest bidder.
