I always wanted a pet monkey, as I've grown up around all kinds of animals as a kid, cats, dogs, birds, pet mice, hamsters, etc). My mom used to raise parrots, and most people don't realize what a commitment they are. She would make people do their research into what owning a parrot entails, and wouldn't sell one to someone who wasn't prepared, she would also do check ups for the first year or two, and keep in contact with the new owners.

I did my own research on pet monkeys, and came to the conclusion it was a bad idea 99% of the time. Parrots can get mean and loud if not given constant interaction, but monkeys can get downright violent! ( don't even get started with larger apes!) There's a youtube channel of a guy that has a small "monkey rescue" and he gives a compelling argument as to why monkeys don't make good pets. (a lot of the reasons you mentioned) Enjoy them in the wild, in videos, or support a monkey rescue group, don't get one as a pet.
