It takes energy to start it, but then it can continue for arbitrarily long
periods with no absolute minimum energy required.

You could from the outside periodically read a check bit, which you allow
those in the simulation to set. And when flagged proceed to read more bits.
Or you simply trust the robots you left in charge to keep it going. There
would be a K*T*ln(2) energy cost each time you read the check bit.

That's no problem, the simulation is self contained. A single program run
on reversible logic gates.

And all this is true of the physics of our own universe. That doesn't make
life meaningless, however.

You let it finish after a million years and pay the energy cost then. But
you got a million years of nearly energy free compute time.
