To some degree, I get the self-interest part --- right before I weaned, I couldn't help but think how much I'd miss bonding with my baby in that way. But I'd think that's just 1% of the story.
The other 99% is really giving so much of yourself that your time, schedule, wardrobe, lifesetyle, diet revolve around the breastfeeding commitment so there's really not much self-interest in that.
There's so much scientific evidence to refute that breastfeeding isn't for the benefit of the baby so I would disagree with the author unless there are a number of legitimate studies to back those statements up.
