Blocking COPY ?

[Richmond]

I really am getting tired of continually commenting out 25 copy commands 
in 25 objects
for Demo versions of my stuff, and wonder if there is not a way to block 
the copy command
globally with a single stack script rather like this:

on copy
    don't
end copy

----------------

I am aware one can do this:

on copyKey
   answer "nice try, chum"
    pass copyKey
end copyKey

although, on Macintosh it does not stop command-C working!  and the 
answer dialog doesn't appear!
