It's less about using fakes to push your agenda, and more about being able to (plausibly or implausibly it doesn't matter) claim that whatever video is a deepfake.
The truth is meaningless, and as tools like deepfakes become more and more sophisticated, it's harder and harder to establish baseline realities.
And someone is benefiting from that shift away from reality, I just don't know who.
which will lead to people trusting forensic experts and corroborating data/witnesses. If you were a Karen caught in an embarrassing public meltdown you could absolutely say that the video was deepfaked and you were really just home alone sleeping at the time, but when 7 different people's cell phone videos, multiple security cameras, two dashcams, 14 ring cams, GPS data captured from your mobile device, and one police surveillance drone all agree it was you that's not going to work out so well.
People made the same arguments about photoshop, but it's really not a problem. Almost never is a single video the only evidence of anything and in the cases where it is and that video can't be verified it's probably best not to ruin someone's life over it.
