INVISIBLE CITIES XXIV -- Trading Cities: CHLOE

1. There's a language issue present in Chloe, very similar to that of Hypatia, inasmuch as words and expectations have practically nothing to do with signs or the reality containing them.  Thoughts?
2. Is Chloe a virtual world?  Where does Chloe exist, especially concerning the all-cities-are-one?  Heck, even this: is Chloe science fiction?
3. If this is a city of commerce, a "trading city," what is the merchandise?  Where is everybody going when they pass each other on the street and "all combinations are used up" in their minds?
4. Regardless of the lack of physical contact, is this indeed a chaste city, let alone "the most chaste of cities"?
