Ground shipping is both a complement and a substitute for water shipping, so the net effect isn’t obvious. (Or at least, it’s not obvious to me).
Also, if a certain interest group has not lobbied in a policy area in the past (as I think is the case here?), then that’s nonzero evidence that they will continue to not lobby in that policy area in the future.

Since overall freight moved wouldn’t change that much (see my comment in this thread), the main economic efficiency of repeal is obtained by using ships instead of ground transport, because ships are cheaper. So overall, ships must be a substitute for ground transport. However, it’s possible that some routes would be nearly all rail right now, and if it switched to primarily ships, there may be some additional trucking involved because it’s not worth putting on a train for a relatively short distance. Have you looked at any studies examining effects on different modes (I haven’t)? If repealing the Jones Act actually did increase trucking, then it could be positive for overall employment as the labour intensity of trucking is so much higher than the other modes.

It does look like ground transport has not lobbied, which is surprising to me, but I agree it does provide evidence that they will continue to not lobby.
