Do keep in mind that this analysis was originally aimed at the IETF community, and was an attempt to examine what I see as a kneejerk reaction of outright hostility among a certain percentage of that community towards what they characterize as "political" activity. Some of their operating assumptions may not be what you'd expect.
For example, if you firmly believe that anyone advocating alternative roots is a scoundrel seeking to make ill-gotten gains, and that their technical incompetence would lead to instability and failure of the net, then you don't really need to spend any energy on questions related to their proposals. Your successful mental appeal for a "motion for summary judgement" rules such consideration out of scope and in such an atmosphere nobody would ever actually feel the need to get around to examining the technical issues at hand, such as the additional load that would be generated by a significant increase in the number of TLDs or the distinction between alternative root systems and alternative namespaces. You've dismissed the person asking the questions before you get around to having to examine the question itself.
The thread currently underway on the IETF general mailing list (of which my posting was a small part) offers me some hope that this situation may be changing. My interpretation is that there is developing a consensus view that the ICANN effort has failed, and because of that the IETF might have to revisit some of these issues. There's still invective and namecalling going on, but also some reasoned thought about the issues. This may or may not lead anywhere, but we do seem to be moving beyond the "off with her head" reactions of the past.
Of course, all this is IMHO, FWIW, YMMV, YGWYPF, VC, DSO and bar....
