If you don't have the mental capacity to see the difference between keeping a 8" fish in a large aquarium, and keeping a damn bear or a tiger, then there's no point in even addressing your comment.
Seriously there are individuals out there with a means and will to keep such animals legally and safely and with respect to the animal. Sadly we don't get any media coverage for these people. While I think exotic animal trade is fine I'm more inclined to recommend some oversight for dangerous animals but I'm always going to be against banning anything. As we've seen with many of the animals that came closest to extinction and bounced back many of them were saved and kept at zoos, businesses, or privately owned.
Punishing and criminalizing good animal keepers for the sins of the bad ones is not good government in the least. I think we should ban computers because some people pirate stuff on them, better yet we should ban guns, ban pets, blah blah blah its just gets ridiculous that stance is indefensible and makes no rational sense.
