As an engineer this is a comically incorrect take. Absolute zero is useful as an absolute reference in the same way zero of anything is. Try doing anything more complex than high school physics and the practical necessity for an absolute temperature reference becomes obvious. For fucks sake they even bothered to make an imperial version. Rankine is just Fahrenheit shifted to have zero be absolute.
