If you use non-constructive reasoning¹ then you can argue for basically any outcome & even convince yourself that it is inevitable. The basic example is as follows, there is no scientific or physical principle that can prevent the birth of someone much worse than Hitler & therefore if people keep having children one of those children will inevitably be someone who will cause unimaginable death & destruction. My recommendation is to avoid non-constructive inevitability arguments using our current ignorant state of understanding of physical laws as the main premise b/c it's possible to reach any conclusion from that premise & convince yourself that the conclusion is inevitable.
