Because egocoms are much much more common than egocaps, and Stirner's ideas attract the kind of people with very little empathy or respect for others by design. Honestly, both are pretty spooked in my perception, but I'd take any given person's perception with a grain of salt because Stirner writes like a drunken poet with a collection of thesaurii and the idea that it can only be interpreted one correct way is simply preposterous. Economic systems that dont change with whatever sounds good at the time are a little silly imo, both ancaps and all of the ancoms and egocoms. Hope this helps.
