Causality is needed as an axiom because if it does not hold, then it means that the result of an experiment could be depend of something happening in the future. That means that we could not have reproducible experiment anymore for instance.

And that would be extremely _surprising_, but there's nothing preventing the universe from being surprising to us.

(We'd still have reproducible experiments and so forth in every context that didn't involve whatever extremely weird circumstances would produce causality violations -- and the circumstances would certainly have to be extremely weird.)

Real world experiments aren't 100% perfectly reproducible already, and this would be a very marginal worsening.
