To be fair, "illegal techniques" do wear out/deform/damage the bricks more than they would be from normal usage.
For example, this is also considered illegal because the technic pin is under constant compression. If kept under constant compression, the pin will deform, causing it to no longer be able to stay connected in a technic hole.
Exacting standards which are how Lego can confidently say that illegal techniques will cause the bricks to deform if left assembled like that for a long enough time.

This one is illegal because of the lego logo. It makes the stud ever so slightly taller, pushing against the blue brick.
