Yes, scorpion venom should be commercially produced with a breeding program, because it can help a lot of people. If scorpion venom is that powerful, it would do many great things in order to benefit society. Also, if people are willing to buy it, it would produce a profit for the people who go into the business.
Of course, scorpions should be bred for sale. we bread cows, chicken, pigs and all kinds of animals for beneficial purposes. Why would the reasoning be any different for scorpions, particularly since its venomous properties are so beneficial to humans. Sounds like a pretty good business opportunity. Where can I sign up?
If scorpion venom truly has healing properties and it's possible to breed them for sale to increase supply, and lower costs, I think it should be done. I'd hope no one has a monopoly on the supply even if it's sold for profit, and that it can help people in need, and that the scorpion breeding can be done without hurting the animals.
Scorpion venom might have great healing properties, but breeding scorpions for sale would be very dangerous. They could easily take over other species or become too large and super dangerous. People should leave scorpions alone and not try breeding them in order to avoid creating a super predator and killing people.
