Exactly WHAT problems?  Be VERY specific.

That is NOT true.  The Leafscan 35 and 45 can scan B&W in B&W.  Drum
scanners, as they have separate channels, can be set-up for scanning B&W as
well.

Again, utter nonsense.  IF you know how to use the scanner, you can get
exceptional B&W scans from an RGB scanner.

Not for me they don't!

I won't bother to address this issue right now...as it is a separate issue.
For *some* people, digital does have some advantages, but not for all, and
as far as time goes, digital can take significantly longer.

The BIGGEST problem is the fact that you are using an RGB sensor, in a Bayer
pattern that only captures %50 Green, %25 Red, and %25 Blue information.
You first have to understand that, before beating your chest about the
(dis-)advantages of digital B&W image capture.  Digital cameras that are
monochromatic are available, but you are apparently not using one, so that
doesn't enter into the conversation.

You can do the exact same to a scanned negative.

Please, have your ducks lined up before attempting to discuss this subject
in an authoritative manner.
