Criticisms of FTL don't come from being a naysayer. We now have more than a century of testing relativity and to date it has made no wrong predictions. So your bar for sayhing it's wrong is really high and the onus is on the advocate for FTL to ay how relativity is wrong and how that can be verified.
You plug -3+2i kg into mass, for example, and say you're not violating Einstein's field equations but you are. You've violated the domain of one or more of the quantities. Now that's fine if you have a theoretical basis for that but there isn't one. It's just hopium.
Likewise, physicists have analyzed the Alcubierre drive and come up with some real and genuine problems like the energy requirements [1].

Human history if full of Rumsfeld’s “unknown unknowns”.
Dark matter seems to make up about 25% of the universe. It seems to obey general relativity (that’s how we inferred its existence), but not quantum mechanics (we cannot seem to interact with it electromagnetically, e.g. see or feel it).
Something is making distant galaxies accelerate away from us. Taken as an amount of energy, that’s about 70% of the universe. It’s accelerating a lot of mass! Often called dark energy.
This is all to say that despite our success with the physical theories we believe in today… we still have some pretty darn big unanswered questions in front of us. It seems a little early to be definitively ruling things out.
I still don't see any point in claiming that a given thing can never be done. What does it help? Our knowledge of the universe isn't complete and I don't think people are starving because others are thinking about warp drives.
I do not see anything going FTL anywhere right now.
Yes, well, you wouldn’t see it, would you?

Other than distant galaxies from each other.
Take a strong laser pointer and point it at one side of the moon. Then flick your wrist to point it at the other side. The laser just "broke the speed of light" but it didn't transfer any information so it's all good.
I don't think the laser / wrist combo is breaking any speed of light limits here.
It's actually "Maximum speed of information". There are things that are FTL, but nothing that carries information is.
Well, that would break causality. I believe if we ever learn how to go FTL (improbable!), it'll still force non-causality breaking. Meaning the place where you FTL'd is not your universe anymore.
