Not the original poster, but the answer I can think of is the mail service. In many countries it guarantees the cost of sending a letter from A to B is the same, independent of distance between A and B or the popularity of A as a source and B as a destination of letters.
That often even stays the case when the mail service gets privatized.
I’ve never heard of such services to originally be privatized, though, or of the service to be privatized to multiple providers (say with one company serving the large cities and another the countryside, or one doing half the country, and another doing the other half)
Also: are you sure this is libertarianism? I would think subsidies can’t exist in a libertarian world because the government doesn’t exist there.
