Yeah, if you assume causality, then tachyons can't be fantastical,
they're only the result of something that is or did.

Nope.  Neutrinos are firmly ensconced in the Standard model of
particle physics, while supersymmetric particles are not.

If you assume lack of causality it's pretty easy to arrive at
itself.

That's the problem with the conventional view of FTL phenomena.
It comes from the Lorentz transform:

u' becomes infinite when u = c^2/v, and infinity is a red flag
in physics.  It means that the math becomes useless at and beyond
that point.  Physicists, who should know better, have persisted
into that real and come up with all kinds of frivolous assertions
like time going backwards, negative energy, causality violation
and a "reinterpretation principle."

    Mathematics really owes physics more and better
mathematics

And the most important  contribution is
announcing the oldest, very important
and successful part false, as it didn't
want to fit some symmetrical delusions
of an insane crazie.
