So I decide to put up a lightning rod, and the lowest proximity effective range I can find is 1 acre. And I need this, WE need this, for our safety. So I am right then to divvy up the cost between my neighbors and I, whether they are willing or not?
As I said, this has nothing to do with ethics. It's about whether the good gets produced or not.
Suppose you can't afford the lightening rod on your own. You'll have to get some of your neighbors to help pay for it. So you go around explaining the benefits and asking them to contribute. They all agree it would be beneficial. But each of them will benefit from it whether they contribute or not. So why would any of them contribute? They all hope that someone else contributes, so they can free ride. Consequently, not enough people donate and it never gets built.
Note that this is especially problematic for a large group. Suppose that the number of contributors required to produce the good is 1 million. If everyone contributes, the good gets produced. If not, not. Is it going to make any difference whether you contribute? No, you're just 1/1,000,000th of the total. You cannot meaningfully improve your chances of getting the good by contributing. So why contribute? And this is how it would be for national defense. It would have to be very large group contributing to the effort. Hence the problem. Security will be underproduced if you're relying on voluntary contributions.
But these things can be done voluntarily
No they can't (see above), which means in an ancap society they won't, which means security will be underproduced in an ancap society, which means an ancap society will be outcompeted militarily by a state (which can force people to pay for security and so doesn't have this problem). QED
And if they can't it is a sign that not enough people shared your desires, and that is no reason to carry out your desires forcefully.
Whether it should be produced is beside the point.
The point is that it won't be produced, which means an ancap society cannot defend itself.
