I'm not sure where your going with that BK, but I don't think its as simple as that. Governments change every three years, but their advisors don't. Successive governments get advice from MAF, or Treasury, or whomever - that's why some things take far longer to change than a government (thankfully). Personally, I'm in favour of erring on the side of caution and I'm OK with not having access to every single critter on the planet. The point I'm trying to make is that there is already a lot of cool stuff here - we just overlook it in favour of what is considered 'exotic', precisely because they aren't readily available. If they were, I suspect they'd lose a lot of desirability anyway.
