Code execution how? How are you going to execute code on my machine if you don't have physical access to it? That's why the RCE makes a difference.

> it would be rather redundant to use code execution as a local user to obtain code execution as a local user, no?

As I understood the comment that started this subthread, it was talking about using a remote code execution vulnerability to modify .bashrc. Nobody, as far as I can tell, in this discussion is talking about having local (i.e., physical) access to the machine.
