Actually, that last paragraph's questions have been sort-of asked and sort-of answered by one of the Sailor Moon Expanded authors, Sherlyn Lim, in a little ditty she called Dressed to Kill (For Truth, Love and Justice, of course). Apart from that, though, I don't think anyone's ever asked those questions before, in- or out-of-universe. In the words of the incredibly notorious Gypsey Davey to the incredibly famous Willy Rivers, they just figure the territory comes with the cowboy hat, or in this case the miniskirt.
