...but i'm sure a biologist such as yourself could put together a list of benign species that would be OK for transportation between boarders as we do with other trades...
Do you have any idea how absurd that is? The amount of work required to do this for even a single species could take a team of dedicated scientists several years and many hundreds of thousands of dollars in expenses, if not millions. Then even after you've wasted many years and quite a lot of money (which you would never be able to raise in the first place, and good luck finding qualified researchers willing to waste their time with this dead end project) generating this report, you'll have to convince a whole lot of politicians that it's worth expending their political capital to introduce/change the relevant legislation just so some completely inconsequential hobbyists who are mostly children with no money or ability to vote can be vaguely entertained until their attention span shifts to something else.
Edit: the more I think about this, the more ridiculous it becomes.
You're proposing that that a level of study be done on random imports to a level of completeness that vastly surpasses the level of study that we have done on the overwhelming majority of native species just to please some money less hobbyists.
You're proposing that there is any way that you could ever possibly convince even one single high level regulator that they should risk their career and reputation for all time by passing a law allowing unrestricted importation of a slightly different version of the same type of insect as the several in the US now that are invasive imports causing significant economic damages just to please some irrelevant children.
You're proposing that it's even possible to study every possible eventuality of a species being introduced into a completely new environment, this environment itself not being exhaustively studied and understood, and declare it to be 100% benign in all possible cases of escape or pathogen spread or any other potential consequence.
You're proposing that even with a magically obtained and legislated list of allowable ants, that the hobbyists currently demanding legal imports would ever be satisfied with a finite number of options when there are tens of thousand of exotic species around the world.
