Owning venomous is "play stupid games, win stupid prizes." I would think medical expenses alone would repel people from owning them as pets. I went to a reptile show and there were several tables of venomous snakes including rattle snakes for sale in taped up cake containers. Owning them requires a permit but I think those people are crazy. I'm surprised, or not surprised, that the owner didn't have anti venom on hand.
