But as I said before, that does nothing to rescue the irreducible complexity of the flagellum. Either it came from a more compact structure, or resulted in a more compact structure - but either way, that more compact structure is also functional, so long as you don't buy into this artifical constraint that only things that do X are "functional". Or, alternately, the TTSS and the flagellum are both descendents from a common ancestor structure, but that obviously belies the irreducible complexity of the flagellum by its very nature.
One could, I suppose, argue that they're both the products of special creation, appearing sui generis, independently of one another as the products of some designer. But then again, I see no evidence to support that hypothesis at the moment.
As I stated, the functionality under question is flagellar not virulence and that determines irreducibility. The argument is not whether something has any function( you can fill a balloon with water, air, or a present).
