A design defect is a problem caused by some aspect of the design. I don't
know why you would consider the effects of propeller propulsion to be
"design defects". They are simply aspects of that type of propulsion.

An aspect of propulsion that constantly pulls the aircraft to one side
sounds like a defect to me.

You could say the same thing about lift, it has a "defective" component
called drag. Why don't you simply design that out? Why would anyone deliver
a defective airplane that came with drag?

The answer, of course, is that we have all done what we could, with what we
have. All real world design is a result of compromises, we don't have a
registry where the drag can be turned off, the p-factor zeroed without other
side effects.
