I visit Sardinia almost every year since I was a teenager, and I've eaten casu martzu many times. Once you get past the maggots (which I hate) it's actually a very good pecorino cheese (my favourite is Roman pecorino cheese, but being from Rome I am biased)
It's illegal because it is considered potentially dangerous, but its dangerousness has never been proved, of course it's safer to simply prohibit it, it's quite popular in Sardinia, but not many even on the island eat it and in Sardinia people keep making it anyway, so I think it was the right decision.
Someone feeling sick after eating it in France would be very bad PR for such a small, local, traditional food.
I know of people that went to Sardinia only to taste it, exporting it doesn't make much sense both economically and beaurocracy wise.
