Is medical technology harmless? It can be used to create biological weapons, and there was at least one media hoax that Saddam had looked into cloning. Any technology has dangerous possibilities, but some are more obvious than others.

Would they? I can very well imagine posthuman idealists continue sending articles to Nature. As Tipler pointed out, in any sufficiently advanced and pluralistic society there is bound to be some people wanting to interact with the primitives for whatever reason.

Look out for the dangerous little word "are". You assume a lot with it. Maybe it is feasible for posthumans to be autonomous and self-contained, but it might not be economical. If posthuman 1 and 2 specialize, they can become more efficient at producing energy/matter/nanotech/fnord than any of them individually, and hence be better off by trading instead of being fully autonomous. It seems that you need to get rid of all profits of scale for autonomous posthumans to be economical.

Can you add infinite amounts of slave modules? That assumes a lot about your cognitive architecture - you seem to have a very definite view of what posthumans will be like, which you base your reasoning on, but which remains assumptions until shown otherwise. As for infinite expandability, that is not obviously possible, can you give any support for it?
I would also like to point out that one of the most useful resources/abilities in a highly advanced information society is alternate viewpoints. Problem solving has been shown to work better if the cooperating agents involved have different approaches than if they are variations of the same basic agent. Diversity is a competitive advantage, which means that a diverse group of posthumans can often outcompete a similar clone of a posthuman.

Note that you here assume that offense is efficient and deadly, which is another assumption that may not hold. If I can hide in space, I will be hard to find while the others near earth will be visible - so your scenario would force all posthumans into total hiding. And if it is possible to protect oneself (for example by being distributed), then MAD may not even hold.

Isn't a posthuman a highly limited creature? It is still subject to the same physical laws, same limitations of space, time, entropy, energy and matter humans are. It may just be better at exploiting them. And as Marvin Minsky pointed out, as soon as there is *anything* that is scarce economics becomes relevant. Maybe you could build everything for yourself given enough time, but isn't it easier to trade with someone who already has?
As I explained above, trading posthumans are likely to be noticeably more efficient at exploiting resources than isolated posthumans. They also have less reason to attack each other, making it possible to focus defenses outwards rather than inwards, increasing their (mutual) strengh. Also, the emergence of posthumans is not likely to be a binary jump (as I have argued at length here and on the transhumanist list) which means there will be a spectrum of more or less trans/post-humans around which have incentives in participating in such trade.
