I mean the short answer is that it doesn’t temperamentally suit him to do so.
Maybe a mid length answer is if you agree with his assessment on say humanoid robots in terms of market and you believe they might have a geometric growth factor in production (eg robots can make more robots) then you’d want that business build out done by a team that can scale rapidly.
For fabs spacex and Tesla are significant consumers of the output- vertical integration is preferred by lots of companies.
