Why not quit the Tour and go for the Giro as a co-leader with Carapaz?
Because its beyond stupid to not race your 3 best riders in the Tour. Bernal is out, Carapaz was scheduled to do the Giro beforehand and still does after the Bernal incident - if anything, we should ask ourselves why Carapaz isnt doing the Tour. Tour de France >> Giro d' Italia. You simply cannot rely on only Geriant Thomas and Adam Yates in the Tour as Ineos.
Edit: Hes looking good for a top-5 this year, and I wouldn't be surprised at all by a podium. Hes just that good. Only the Giro-guys and Pogacar was missing, and he was consistent through the whole week and was the strongest on the hardest stage. He now has a Dauphine and a Pais Vasco to his name - in my opinion, the two hardest one week races to win these days and as a result, the two most prestigious one week stage races in my book since a) field is always good, b) the route is always super hard and c) the racing is always super hard.
