I wouldn't call it nonsense. If the comparisons with the virial theorem and energy isn't enough to consider it at least as a reasonable choice, at least you should consider it as such because John Baez agrees with it.
I'm attempting irony. The tone of the manifesto is a bit breathless, putting up interesting enough considerations in a overwrought manner, with half-hearted efforts made at looking at the issues raised from more than one point of view.
Draft one of my lambda manifesto shows that the only consideration of conceivable value, namely ease of defining a transcendental by means of a convergent series, leads to only one possible choice of fundamental trigonometric constant, lambda.
And you don't mess with John Baez ;-)
