I’m a bit lost what we’re arguing about here.
couple of things.
seems to be a misunderstanding that an engine (piston, rods, crank) that can't be perfectly balanced (by adding/subtracting weight to those parts) can't be balanced using alternative technique (say balance rods).
Similarly, taking the inherently balanced 4-cyl, you have described the rather complex Phaser oil pump (a bizarre looking device).
There are many sources of vibration in an engine (eg every cam lobe). Changes in ignition timing alters how vibrations interact (at some time they will add, at others they will cancel.

My point is that the engine you drive down the road is a little more complex than the minimalist "piston, rods, crank"

I really am at a loss as to why you keep banging on about this. What point are you trying to make?
