Well, as long as you consider them "gaps" in need of a "justification", of 
course that argument (and the one about the "gaps" themselves) will of course 
seem singularly unpersuasive. 

But if you see them as a "feature" (that may sometimes, albeit rarely, 
missfire), then you would have no problem with /either/ argument.
