Also, you can run the copy inside a virtual environment and then
the copies will never diverge.
?? I don't think so. Insofar as they are classical objects they
depend on decoherence to remain classical and deterministic. But
that means they interact with the environment. So the
environments would also have to be identical at the quantum
level. But then how would you interact with them in order to
measure the behavior. So I think the virtual environment can only
give a small extension in predictability.

It doesn't follow that the environments have to be identical at the
quantum level, as that would imply that one cannot build a reliable
classical computer. The whole point of computation is that you are
able to take as input only that is relevant from the environment so
that the outcome of the computation is independent of other factors.
Good point.
I agree. Almost the essence of computation.
