While I can respect the opinion of "..why? we have so many beautiful native animals" I can't agree with it. Sure we've got some nice stuff that people who can import herps into their country would love to get their hands on, but there's so much more out there that we'll never get to work with. It sucks to me that there are so many different reptile species in the world, and we'll only ever get to interact with native ones. I'll never get to feed a chameleon,see the ferocity of an ARP, set up a forest enclosure for an iguana, or own something as beautifully deadly as an eyelash viper.(Yes, I realise one could find an Australian equivilent for the aforementioned). There's more to herps than what we've got in Australia.
Sure, I could just work in an animal park, but it doesn't compare. I think importing could have some good points. Those of us (the majority of keepers I suspect?) who can't afford GTP's or womas, or blackheads might be able to get something equally impressive (in colour,in their own opinion) like a ball python for alot less money. That is assuming they're imported in bigger numbers than just 10-20 animals. I realise that there's alot of keepers who are strongly against the idea of breeding herps to produce different and unusal colour lines (which is fair enough), but then there's all those people who are involved in the black market trade who pay big bucks for it. Making exotics legal would have to have a big effect on this industry. If you import in unusually coloured animals, there's no way no-one will buy it.
It'd also (I think) make herping more popular, by offering people more variety. But then again, that could be a bad thing.
Offering the general public something like a designer ball python could lead to animals dying due to lack of care, or high dumpage rates, like gbskda said. I mean, a lavender burm's cute when it's young, but what do you do when your kid's pet takes up a whole room and tries to eat your kid? Just look at the dumpage rate in the U.S.
I don't know how importing could be regualted properly, or who would do it. I don't see how they'd stop wild herps being taken and sold, even if we were only allowed to keep CB animals. And even though I've ranted on about how it'd be good to import, I don't support it, not unless they found a way to stop WC animals and diseases being imported.
Meh, either way, if you want an exotic bad enough, you can still get one, legal or not.
