This probably needs to be dealt with on a case by case basis. Spay and neuter the ones in the Everglades to keep them from reproducing, and make stiffer penalties for dumping these snakes.

There's no way the government can control every scenario anyway, so there has to be a better alternative instead of bans or sweeping "big brother" type regulation.

What individual citizens can do preventatively is to educate people on the care of these animals, and maybe come up with a back-up plan for where they can go if some owners can no longer keep them at some point so that they don't dump them in the wild.

In fact there really should be some breeders on channels like Animal Planet doing educational TV shows about snakes. Instead of the fear-mongering shows painting them as bloodthirsty creatures just waiting to squeeze the life out of you, these shows could show snakes that are tame and show people what each species needs to be well cared for. That would go a long way towards a real, long-term solution.
