Ambiguity of legal language doesn't mean you cannot figure out if a certain phenomenon is legal or not. For example, how would one write insurance contracts? Is it possible to write out every single eventuality? No, so the solution is generic language. There are of course badly worded laws, but it does not mean that everything has to be concretely written out.
