As for your file example though, you do demonstrate why one may choose
upper vs lower case, Windows does allow that.  But should they be

Well, you get to choose the filesystem you use.  JFS2 if I recall could
be case insensitive, but i would play havoc with the OS if you used it
in the wron place.  In Windows, can you make it case sensitive?
 

However, I agree with your comment about unicode.  Treating upper and
lower case letters as the same, leads to complicated rules, which may
vary from system to system, and cause chaos.

Unicode seems to have come up with some standard set of “default” rules

 These would need to be in a standard, one that filesystems can
implement.  But then filesystems would have to implement the same
standard, otherwise, again issues arise.  Can't see this being workable
for end users.

   So, in essence, the development of case-sensitive
   systems ruined it for case-insensitive  :-)
   Same now for space-tolerant file names.
