So how does he define the RGB the scanner creates to bring that RGB into
Photoshop or to convert to any output space? The role of the profile is to
define the RGB, not correct data or take over the role of the operator.
Assuming he has an untagged scan, how on earth does he know what to use to
covert into his RGB Working Space? Does he make the asinine assumption that
the file is in his monitor RGB to convert to other spaces (like an output
space)? Does he simply assume that whatever RGB is coming off the scanner
somehow matches the Working Space? If so, he's in for a rude awaking.

So the profile for the Monitor is OK but not the scanner? Why's that? What
makes him think that the data in the scan is being properly displayed on his
monitor with out defining both the RGB in the file and the RGB of the
display? What makes him believe that without knowing the data in the scan
(with a profile) the preview he's so sure of is even remotely correct?

I can think of a number of scanner manufactures that would not agree with
this at least in his simplistic explanation.

It is ridiculous.
