Good dissertation. But I was not arguing about what you've said.The speed of light vacuum. Physical particles can travel FTL in medium like water.

"they are assuming, in my very humble opinion, that there are no new physics to be discovered on this issue"
I don't think that's the correct assumption at all. The gold standard is evidence. There is no evidence of new physics discovered on this issue in any physical theory of the known universe.
If there was evidence, theories would instantaneouslyhappen to explain it as we saw with the FTL neutrino joke.

Think about it. Once causality is broken, free will is also lost.
