Tipler et al. actually once proved some powerful theorems about open
universes, showing that it was not possible to close them by
rearranging the matter inside.

Sure, but that is not good evidence for Tiplers position. If he had
made a plausible sketch of such a system or showed some theorem that
implied the existence of high-energy complex systems he would be on
much steadier ground. Now he is just assuming that it must be
possible, a bit like a space program assuming that before landing we
will have come up with a way of landing softly...
