That is the same to ask "why do you want to access the
filesystem" or "why do you want to allocate memory" or "why do you
want to know the exact position of the mouse" or "why do you want to
print a file to a printer" or "why do you want to display graphics"
and so on and so on. In few words: it's the very reason of existence
of computers -- to access the exterior. One cannot compute in a vacuum!

Oh, no doubt about that. I love X design. It's really well
designed. Although it seems very complex to me. I guess that it is
inevitable at that point. The level of competence is too high --
Xserver on one machine and the client in another one.
