It's simply a consequence of our physical laws rather than something that's "enforced". And Relativity tells us that anything travelling faster than that would allow information to travel back in time, thus screwing up cause and effect thus our universe wouldn't exist as it does.

There's nothing logically impossible about time loops.

  Except for when they create logical paradoxes.

    The universe doesn't enforce logic in the form of twins paradoxes and all that tomfoolery. Spacetime is a physical object not a logically consistent human centric clone enforcer.

Do you know any simple thought experiment that shows this "ftl means information traveling back in time"? What I've seen is that ftl travel breaks causality in our MODELS of spacetime.
