  As a consequence of the spacetime structure, defined by the tetrad field
instead of the metric tensor alone, $f(T)$ gravity seems to harbor its own
chronology protection agency. When Gott's pair of moving cosmic strings is
considered, it is shown that the requirement of having a global parallelization
-- i.e. a global smooth field of tetrads -- drastically restrict the form of
the tetrads on the junction surface between the two strings. The junction
conditions on the tetrad field are satisfied only if the corresponding boosts
needed to put the strings in motion are null on the matching surface. This
seems to throw overboard Gott's construction from the outset without the need
of analyzing the divergence of the expectation value of the energy momentum
tensor on the Cauchy horizon, evading in this way bothering quarrels concerning
the choice of vacuum.
