Why don't people indent C++ access specifiers/case statements?

Question

I often see stuff like this:

class SomeClass {
public:
    void someMethod();
private:
    int someMember;
};

This seems totally unnatural

Answer 1

Because public and private are labels which don't introduce a new scope, I prefer not to give them any special indentation, thus:

class foo {
    public:
    void something();
    void something_else();

    private:
    int top_secret;
};

This way, the consistent indentation rule is "indentation equals scope".
