Deliberately going back to a preindustrial society in the end means deciding who is going to live and who isn't (including both currently living human beings and those potentially born in the future). Who is to make that decision and on what grounds? By the way, intentionally rewinding to a preindustrial society technically is a candidate for the Great Filter, too. While a civilisation that does this will survive it won't be discoverable anymore in order to provide an answer to the question "Where's everyone?".
