Sorry, I wasn't trying to be condescending, just making a little joke.
To be clear, I did not say, nor do I believe, that an armboard can provide sufficient isolation from an excessively noisy motor or bearing. In fact, I explicitly said just the opposite: that an armboard should never be considered a "band-aid" for a noisy motor or bearing, which I think is the point you are trying to make. I can't speak for what others here believe.
But the mechanics of the materials used for armboards are not exactly irrelevant either. The kind of material used for an armboard (or plinth) will determine the degree to which vibrational energy is absorbed or reflected, and can also change the frequency of vibration due to the impedance difference between different types of materials. That is in part why a stainless steel armboard or plinth will have a different sound than one constructed of maple or carbon fiber, and acrylic will sound different still. This is true even in cases where the motor and bearing are extremely quiet.
