Indeed, two such mechanisms that would largely circumvent the issues around CTCs and invalid Lorentz transformations and such entirely - Alcubierre drives and wormholes - are barely mentioned. (They don't necessarily circumvent the problems around infinite energies and/or zero/negative masses being apparently necessary, to be clear - I can't imagine the amount of energy needed to create and stabilize a wormhole or warp bubble to be all that trivial - but it's pretty obvious from their very premises that they would not inherently produce causal paradoxen).
