"turning a garment inside out before washing it will prolong its life because the agitation of the washing abrades the outside surface"

Pretty sure that's not true for front-loading washers. No agitator, just tumbling. Uses less water and higher spin leading to shorter drying times and less energy.
Easier to load and unload rather than trying to reach over the top (especially if a small item is at the bottom).

But if the garment is poorly made, nothing really extends its life.
