Government mediating equal access to last mile lines and funding their construction — probably good to everyone.

Government running consumer ISPs end-to-end is a tougher sell.

Private business should justify itself by doing better and ensuring nobody wants the public version -- which also ensures the public version stays cheap. [Expensive per unit, but inexpensive overall]

>" You can get you own armed guards - but you will still subsidize other people's police force."

Why? This is an especially open question in areas with large police forces and high crime rates, or histories of police abuse of power.

>"You pay taxes to provide a minimum service to all of the community, you can then take advantage of it or not - that's your prerogative."

Again, why? What's 'a minimum service to the community'? Do you mean public goods, or services that have positive externalities, or things that help the poor?

>"I pay for school taxes, but I don't have kids - should I get my money back?"

Maybe! Depends on your beliefs surrounding political authority and ethics.

Perhaps you might do better to point to your ethical framework, and highlight what it means with respect to municipal fiber.

Not should it. An ideal government functions to help the people not individual persons.

I see national defense and public schools as very different. Defense is a non-excludable, fixed cost, so-called ‘public good’. Primary and secondary education are not public goods, though they may be long-term investments (which defense is not).

I am not saying that I ‘like’ or ‘dislike’ either, but they’re very different.

>”An ideal government functions to help the people not individual persons.”

I’ve never heard this argument before, could you please elaborate, or point to a good source for your “ideal government” ethical framework?

Ironically a functioning police service is a necessary condition for far-libertarianism to exist. It is a self extinguishing ideology.
