And again, most people don't have Servants because the HGW is a fucking niche joke that maybe 50 people ever have participated in. In a world where mages have robots and hommunculi and puppets that are indistinguishable from a real human being down to the atomic level, there really is no reason to go through the trouble of summoning Servants to fuck. Just make a doll or something.
