The REAL argument against it is that it will mess up OWL-DL, or at any rate it *might* mess up OWL-DL.

I agree that literals can be subjects. In any case they are, because you just can take an inverse function from a thing to a string, and you have it.
But I do think
'London' a x:Place
is bad design because really 'London' is a string and not a place.
Now of course x:Place my be the collection of names of places in english, in which case it is ok. So it is difficult to say just like that. There would have to be quite a lot of education in the when is it right to use strings as subjects space.
