Jon Irenicus:
Exactly why would this person not simply associate with others who share or tolerate his views? Why would he be inclined to blow up others who've done nothing wrong, and merely do not want to associate with him?
Your premise is that everybody acts rationally. Sure, a rational person is not going to blow anybody up, but is going to resolve arguments verbally or by using the market, non-aggressively. But if we base our predictions on solely rational acts of purely rational individuals, we may as well use Keynesian formula magic to determine the outcome of economics.
Let's assume my highest goal in life is to gather a ticket to paradise which, as my holy book or my holy interpreter explains, can only be achieved by blowing up some not-so-religious folks. I'm therefore rationally inclined to blow people up by an irrational demand from my religion. Rational thinking, when being misused, does not prevent violence, but may actually stir it. Man's ability to use his mind is no panacea against violence and bloodshed.
Jon Irenicus: I can conjure up any number of hypothetical absurdities. Oh, what if the aliens land on Earth? THEN WHAT?!
The scenario of a fanatic engaging in terrorist activities is still somewhat more probable than "what if the aliens land on Earth", I think.
Jon Irenicus:
It can't, because...?

Of course, in an anarchist society, one
could still expropriate the terrorist. However, this person would be committing theft and, depending on the value of the bomb / WMD, is likely to encounter high compensation charges. A statist society could mandate government theft to uphold peace and order.
I'm aware that government theft is not the height of moral action either, but as I said, I'm a utilitarian on that matter. I'd rather have a government violating rights than a terrorist killing masses of people. Of course, it always depends on the degree and usefulness of rights violations as well. One shouldn't fall for slippery slopes.
Stranger:
There is no way of preventing a terrorist assault in any society.
As I said. But it's possible to lower the chance of an attack by using government force.
The question is whether the means of an anarchist society are as powerful in preventing terrorist violence as those of government monopoly of force. I'd say no, due to the non-aggression principle which bars individuals from preventing disproportional damage in spite of possibilites (e.g., I may not rob the terrorist of his hazardous substance even though it may be beneficial).
