Doesn't the concept of Wormholes, folding space or Warp engines bypass FTL blocks?

You're essentially relocating from one location to another by bypassing the distance... Leaving this universe long enough to travel a comparatively smaller distance/time in another then pop back into our universe a long long way but short amount of local time later.

Sure you dont travel FTL but you do arrive in the location Faster than light would take to travel in mundane space.

I believe all of those violate causality, at least if you have more than one of them (more than one pair in the case of wormholes).

Causality might very well be locked to this universe/space.

I mean its all just sci-fi at the moment. But lots of things we take advantage of today was at one time in the past as well.

I prefer to be optimistic about potential breakthroughs.
