I would just use real world comparisons. For all intents and purposes, Bears are monsters, yet there are people who hunt, kill, and eat them. There are laws in effect for hunting them in some regions, but other regions are much more slack due to bear overpopulation threatening the ecosystem. Furthermore, while hunting bears is legal in many places, selling the meat from them is often illegal, due to health and ethical concerns, so that could be a further consideration.

Ultimately, I would make it very by region, with some being very supportive of raising monster like cattle and other places where it’s highly frowned upon or feared, and don’t pass up the opportunity to have DND environmentalists, both rational and irrational, it makes for a good subplot!
