That is exactly the problem we had in Florida when they made it illegal to buy, sell, trade, give away, or own (unless grandfathered in) red eared slider turtles. That species is a real problem in a lot of the world because it does so well in a variety of climates, making it very invasive. They have already become naturalized in most of Florida, mainly because of people turning them loose, as far as I know. While nobody is scared of them, they do compete with native animals, and eat native plants and animals, too.
The problem is that local herp societies previously took in unwanted turtles and found them new homes. And if the state had decided to make it illegal to SELL them, but not to give them away, then no new ones would become pets, and the unwanted ones would eventually find homes. The problem would solve itself, in time. But in its great wisdom, the state took away our ability to legally find them new homes. When I asked the state fish and game person what we were supposed to advise people to do with them, they said they hoped that the person would just keep it, send it out of state, or give it to the state for euthanasia, since it is not legal to give it away or release it. So I told them those words, and most said they would go ahead and release it, just making sure nobody was watching.
And that is how government wisdom in law making usually works, especially if it involves bans on ANYTHING. So be careful what you wish for if you want the government to regulate anything more than it is already regulating it. And don't count on them to either involve people with any real knowledge of the subject, or to listen to them if they do consult them. A real shame, but that is how the system works. The feds are usually worse than the states because they have more money, more power, and because the ability of a few individuals to affect the outcome is often less than in a particular state - unless you are part of a group with a LOT of money to buy influence, that is.
