comment Nonseparable Hilbert space
Again, none of these quotes address what is wrong with doing physics on a nonseparable space. Is there some physical result that holds only for the separable case? The reason I asked this question because in LQG you generically get nonseparable Hilbert spaces and this fact is sometime used to criticize LQG. I wanted to know why that should be a problem.

This answer doesn't really address what is wrong with nonseparable spaces.

comment Has unnaturalness motivated new ideas in physics?
That's what I suspected. I don't know how much faith to put into this sort of naturalness arguments as they are more philosophical than physical. I was trying to find out if there have been any precedents. From the long silence to my answer, apparently there is not.

I wonder where did the other answer with the link to Greenberg's paper go. Was it removed due to copyright violation?

@Vibert Thanks, that's how I came upon this term in the first place.

Thanks. Can you give me an example of generalized free fields which are not free fields?
