It seems to me that determinism is the simple answer to this. If we're all basically just actors playing out a predefined movie then time-travel is just a loop within that movie.

Forgot about that model - one timeline, but your time traveling was always a part of it - this also is functional, but plotwise usually just amounts to a twist rather than something more interesting (i suppose tenet is a bit of an argument against that)
