With respect, I disagree. Musk is obsessed with the "the best part is no part ". Which only works if you don't actually need it. Combined with an obsession with cost cutting, and you get tunnel vision insisting on a course of action which does not know with 100% certainty about the world it is trying to navigate. And this has led directly to people dying.

Being obsessed only works when you turn out to be right, and tesla's system does not work as well as lidar.
