That would be misleading, unless you count among the assumption the
negation of the other two possible conclusions one can draw from the argument.

There could be a very small fraction of races that are running
ancestor-simulations without us having to think that we are living in a
simulation.

If there is no bottom then everybody is living in a simulation.
