The errors can be disabled with the variable kill-read-only-ok,
which the Emacs 20.7 manual does not mention.  (Tried "s" in Info.)

I have a brother who doesn't like Emacs.  He uses an editor that
has the cut, copy and paste functions accessible as "-+*" in the
number pad.  He never uses the copy key -- he just cuts and
pastes right back.  Now what do you make of that?

I don't see a conflict there.  In both cases, the cursor goes to
the end of the line (unless you set kill-whole-line); but if the
buffer is writable, the line has become empty.
