Full Idea
If Fs are incapable of spatial location, it is impossible for a and b to be at the same time in different places and yet be the same F.
Gist of Idea
If F can't have location, there is no problem of things having F in different locations

A Reaction
A passing remark from Hale which strikes me as incredibly significant. The very idea of a 'one-over-many' is that there are many locations for the thing, so to conclude that the thing is therefore non-located seems to negate the original problem.
