It is not a finite list of rules. It is an explanation of the values (eg, respecting diversity) and a list of examples of things that are obviously prohibited. It is explicitly "not an exhaustive list of things that you should not do", and although it does list some _examples_ of things that are prohibited - it provides examples that are "not limited to" the ones provided.

This clearly reduces the ambiguity in the community. And even if some ambiguity does remain - which, as you point out, is inevitable - having examples of obviously impermissible behavior and a framework for conflict resolution is requisite for a community.
