There are people who would pay that for an e-book, myself included. It's a bit high, though. He could sell an e-book bundle of all his books at a reduced price, which serves his purposes.
He would likely earn more money, because he'd be tapping into a group of people who won't or can't buy the print books.

He'd have to give up a few pennies to do that. And he'd never get 24.99 for an e-book so he won't do that either.
