Python very much lives up to its goal of being a language for consenting adults. It's part of the culture that you don't write code that tries to forbid users of your code from doing "wrong" things and such efforts are mostly futile anyway. You can reach right into a Python object's internal data and modify it directly, taking away __setattr__ is just a suggestion. It's the same as in C where you can modify const variables if you're determined enough.
