I presume what Prof. Perelman meant was that once
created, information can be used by additional
persons or additional times without cost, unlike
depreciable capital or 'exhaustible' consumption
goods. Conveying or preserving said information
via the printed page or the byte is another
matter and possibly not zero in cost.
You might be alluding to the point, with which I
don't disagree, that the MC statement is trivial
in light of the definition of information, sort
of like saying a firm arse tends not to sag.
