I think the International Statute of Secrecy is a very important law, to protect Muggles and Wizards alike. First, Wizards are prevented to use magic on Muggles, who are very defenseless in this case. I mean, without the law, wizards could take advantage of Muggles, rob them, make them work for them, you get the idea. Of course, that might still happen with the International Statute of Secrecy in place, but it makes it harder and the prospect of punishment might even work, too.

On the other hand, Muggles could take advantage of Wizards and therefore Magic, as well. I'm thinking of Muggle dictators using a wizard or two to suppress their people without other Muggle countries even able to figure it out.

The exceptions mentioned in the books sound reasonable to me. If there's a life threatening situation and one uses magic to safe one's own life while Muggles are present or to save the Muggles' life, it is reasonable to use magic and breach the statute.
