the point to owning the vemonous snakes is because they look cool, before I saw them in person, I thought it was kind of stupid myself, but after seeing a cobra hooded up right in front of me, it was pretty sweet. No, I'd never own them, but they're great to look at. As for the venom. Most (if not all?) that are kept in captivity and not in a medical place for producing anti-venoms and such. Have their glands removed so they produce no (little if done improperly) venom and their only damage is then in the bite itself.

Who would buy the venom anyways? O.o A side from medical purposes, but I don't think they'd buy it from private owners.
