I think a lot of people miss that federalizing things creates a monopoly, and it's less different from a private monopoly than we might like to think.

It is a democratic monopoly, but democracy among 300+ million people is a big hammer. Do you really, actually think that this will be a well-run service where mistakes are quickly corrected?

No. It will just be an extra layer of protection for any mistakes that are made. At least private companies have to fear the government at some level... who does the federal government fear when it does somethihn unfair? The voter? Hah.
