EDIT: It’s like saying “I don’t take the bus! I ‘self-drive’ my own car! (By which I mean that I employ an agency to provide a driver to drive a car for me, which I rent!)” or “I self-grow and self-harvest all my own food! By which I mean that I pay a farmer to grow food and harvest it for me.”
Words have meaning.
