I don't see any explanation in your comment of how any of those aspects would be worse.
You say "Apple wouldn't profit much more from the switch" because of the volume discounts they get from Intel, but you don't cite exactly how much of a discount they get, and you still concede that Apple's own ARM chips might have a lower cost.
You say "battery life would go up a bit," and seem to imply that it could be up to 20%, which in my opinion is massive.
And you don't address size.
How then are any of those aspects worse? Even under your own seemingly pessimistic estimates, cost and battery life would improve.
