I disagree. Whereever point is, it should report the character after
point which is accessible (this is, visible). Perhaps it makes sense
to add a red warning message in the output of `C-x =' that point is
not located right before the displayed character.
If we had a small line instead of a blinking, block-like cursor (as it
is used with, say, OpenOffice), I could accept your argumentation.
But the visual effect is overwhelming, and it is extremely confusing
if the optical appearance differs so much from the `theoretical'
result.

Hmm. IMHO, the same argumentation as above holds.

Indeed. But for my particular needs -- filtering out some lines, then
searching and editing the visible ones only without accidentally
editing invisible stuff, it seems that `intangible' is still
necessary, and probably will stay so.
