Don't break your arm patting yourself on the back regarding what I know or
do not know.

Digital sensor technology is hardly static and will continue to evolve. What
on earth makes you think that the current technology is the end-all?

Please note that an optical low-pass filter can perform the bandwidth
limitation required to prevent aliasing.

AT THIS TIME some sharpness will be lost by applying such a filter. In the
future this will not be the case. I'm sure you're up to doing the math.

This is NOT hard. Many of us would be tickled pink to get images at the
current best-case digital sensor resolution. Sure, they would not be the
ultimate sharpness the lenses can deliver - but I'd bet that very very few
of us shoot all our images from a tripod or hand-held at 1/1000th of a
second where the lens actually can deliver the best image quality.
