I want to agree, but I've seen the result of this as well, such "single modifier" principles. You end up with a bunch of code that hides variables only to expose a set_x( value ) { x = value; } function -- missing the fact that it makes x a shared mutable variable.
Though I'd say the notion of ownership and control is important, and should be on a list of essential knowledge for programmers. Just like lifetime and visiblity, it plays a major role in where variables are defined.

We're a place where coders share, stay up-to-date and grow their careers.
