  The problem is that in order to extend Chomsky’s syntactic approach to account for such category mistakes, one would need very specific selectional features such as ‘+/-grape’ and ‘+/-sock’. Of course, this is not a decisive argument against the syntactic approach—perhaps syntax really should be enriched with such a wide array of sectional features. However, it does undermine the claim that the syntactic approach can be executed using independently motivated syntactic machinery, as clearly no (other) syntactic phenomenon requires sensitivity to whether an argument denotes a grape.
