That's a specious argument if I've ever heard one.

Unless you're already FUBAR (skidding) by the time you hit the brakes, the
wheels tend to follow one another on each side of the car. In other words,
it's extremely difficult to be in a situation in which you have just one
wheel with poor traction when you need ABS.

More likely, BOTH wheels on one side of the car will have poor traction,
and ABS won't perform any better than hard braking without it. You're going
to have directional control problems in any case.
