At some stage (effective) blur (and decentering) gets just amplified in terms of pixel spread (not according to the same print size).
If I've a blur spread of 2px @ 12mp it gets multiplied to some degree. Where's the point ? Digicams have long departed from a point where an image is really pixel sharp.

Digicams meaning compact digital cameras? Of course they are not pixel sharp at 12mp at tiny sensor formats... wide open they already feel diffraction softening big time.
But that is not the case with APS-C, now is it? Sure, at f14 we won't see a big difference in print between a 10mp APS-C sensor image and a 24mp APS-C sensor image. But the 24mp sensor is not limiting anything there either. At f2.8, or f4, or f5.6, that is then where one still can take advantage of higher resolution.
