I agree with that.    (02)

I also see no problem about quantifying over fictional and
mythological places and beings.  You just create a model
of them (use set theory, if you like), specify how they
interact, link them to your virtual reality software,
and quantify over them as you please.    (03)

All such things can be handled in the same way that
computer scientists quantify over data structures.    (04)

There is no difference in principle between letting
quantifiers range over the planned items in a bridge
that has not yet been built or the entities in some
hypothetical world or situation.    (05)
