None of this negates the usefulness of increased regeneration while sleeping. Sometimes you have better options, sometimes you don't. Sometimes it's a risk to sleep, sometimes it's not.

Like his idiotic suggestion that no one should every kill lumberjacks ever because he doesn't.

Your idiotic suggestion that one should not sleep is exactly like that. For the same reasons.
