Meinst Du dass die Homs sets sind, oder?
Man braucht ja nicht, dass die Objekte ein Set sind. Insbesondere erlaubt iuns das die Kategorie der Sets zu definieren (also beides klein und HSet).

What one calls a category should be a set in the HoTT sense,
i.e. validate UIP, but not a set in the sense of size.
Every deviation from that should be signalled by some adjectives or
