$5 says a third party brings up causality as a counter argument and this never gets looked into again.
(Just to note, I have nothing against causality itself, just the insistence that it has to apply to all observers, even ones far enough that the speed of light becomes a significant factor in observation. Why would someone at Proxima Centauri seeing me apparently arrive at Alpha Centari A before I leave Sol prevent me from traveling from Sol to Alpha Centauri A in a matter of a few weeks? I’m not talking about any other barriers to FTL travel, just this absolute causality stuff. But every time I ask about it, I just get told I’m an idiot for even asking.)
