All of the arguments for it being possible are essentially equivalent to "it could be that we are all just a simulation program, and within that program its possible to pause/change properties/unpause and make something appear as FTL travel within the simulation".
This could be the case in reality. But its utterly useless information, because it doesn't really give you a direction in which you can even begin to investigate it. Saying that something is possible in this regard is saying that our knowledge of our reality has holes, and "anything" can be in those holes, nothing about the specifics of what could be in those holes.
