These have remained unresolved questions, for me, for decades. When an internet pal was trying to found a libertarian (what noun should I use) locale, in Awdal in Somaliland (that detail of whether it was really in Somaliland or not was more debatable at the time), he first founded the Awdal Roads Company.

So obviously there are theories about how these things can be privately funded. But I can never remember the theories. Looking at that link, it was going to be toll roads. People dislike this, understandably. One problem with private roads is that you can't exactly use a competing road, which might entail moving house, or changing your plans for the day, or your job.

I have a vague notion that roads could be funded by a group of businesses that benefit from them, sort of like the W3C or a mall. Non-profit, sponsored roads, or something. (Now I'm thinking of runestones, several of which are near bridges and say "He made this bridge for his soul" or a similar statement.)

Don't ask me about police, I don't even understand crime and punishment, really.

I should maybe add that I meant "We should just naturally have the natural things that we naturally want" somewhat unironically. I feel that way, the same as anyone else. The difficulty, as observed up the thread, is in working out what's natural, or vital, or wanted and feasible. There are no pixies to magically know the answers, to my regret, only governments, and they only pretend to know. By buying and selling we can almost figure out the answers, contingently and approximately, but a lot goes wrong with that, including the friction of having to do it all the time, and "rent-seeking", whatever defines that really.
