Yes. Having both legal and illegal animals available for the public only confuses the issue for USFW policy. It becomes very difficult to trace the source of animals. Afterall, I could say mine bred, and then go and collect about 30 more animals and say they are the offspring. Likewise, someone else could go collect a bunch of animals and say they are captive bred from me or someone else.
Finally, there's the issue of public support. A. cingulatum, for example, is found extensively on pine plantation land and it directly affects that industry. It's very hard to convinve people they need to be protected in the wild if there's a thriving captive bred population.
Why shut down my business over a salamander when I can go on the internet and buy one for 5$? It's not like they're going extinct, right?
