This is what you're trying to convince us of?

Don't put words in my mouth. Aftermarket pulley's have not shown to be a catalyst of engine failure for our specific engine.
The stock pulley is not a harmonic dampener to remove potential damaging frequencies.
The stock pulley with the rubber dampening sandwiched between the cast iron pieces is for N/V/H and balancing of the pulley it's self. The pulley is also balanced afterward by tapping.
Torsional effects are mitigated by balancing the entire rotating assembly and adding counterweights to the crank. No external balancing was necessary.
Engineers that work on designing and manufacturing factory engines have advanced engineering to the point where in most cases, external balancing and/or harmonic dampeners aren't necessary.
I don't take your quotes out of context, please award me the same.
