The original question was about redefining ESC.  How to do that
without making Meta undefined is a separate issue.  (ESC by default is
the prefix key of the Meta keymap, so it's a small wonder that
redefining ESC breaks Meta.  You will have the same effect if you
redefine C-x: all the C-x sequences will stop working.)
