I was solving the problem given.  If you want a different answer, give a
different problem.

You can think that way if you want.  It will give a suboptimal result,
as I have proven.

Your challenge, if you choose to accept it, is to produce a properly
specified optimisation problem for which the optimal answer is an
exponential growth with a small factor (ideally phi, but certainly no
more than 2).

Okay, lets just throw all maths out of the window.  When he starts
sending text, we allocate 6 MB - enough for about a million words.  If
that's too little, we abort and claim he cheated and used
computer-generated words.  Since he can't realistically prove that all
the words were written by humans, we win.
