Yes. I've mentioned occasionally that if the substitution level is quantum,
then no-cloning may be a problem, at least in principle. The usual answer is
that the subst level is WAY above quantum - that our experiences and hence
the famous "observer moments" aren't anywhere near to the Planck time or
length.

If the substitution level is quantum then no-cloning may be a problem
in practice, but not in principle.

The no-cloning theorem would rule out quantum level substitution *in principle* as far as I can tell.
