It more seems like an inefficiency to have ready made milk ready to go at the right temperature but then choose instead to extract it from cows, ship it twice round the country, add chemicals, dehydrate it, ship round the country again, bring it home, rehydrate it, heat it up, then cool it down and finally give it to the baby.
This. This is why I can't understand people who think it's easier to FF (by 'easier' I mean exactly that. Obviously I'm not including anyone with a medical/mental health reason here). I've done both, and FFing was a million times more faff, not to mention expensive. Sterilising, making bottles, heating them, getting out of bed in the night to get them, having to ensure I had enough formula/bottles with me everywhere I went... it was a huge PITA!
Then there is the general 'oddness' of doing exactly what the poster I quoted says.
I honestly don't care how people feed their babies. But I do have to wonder (again, speaking only of those for whom it is a pure choice) if they've thought it through.
