Nope, that's wrong. The argument says that *if* you use an unreliable
channel, then such-and-such can happen. Note the difference between
a premise and a conclusion. The question of whether reliable channels
exist or not is a question of physics, not of algorithms, and this proof
does not purport to show that reliable channels cannot exist.
