Humans spent thousands of years in a pre-truth world believing all sorts of crazy things, and many of those societies produced great things and had people living normal lives. It's only been the last 100 years or so that people's perception of reality has been anywhere close to accurate. And even then, most people believe plenty of things that are false.

I agree with this, but consider the drawbacks to rampant disinformation and the proliferation of deepfakes (all this is IMO): it will make any video or audio deniable and unusable as evidence. Real images will be denounced as fakes. Fake images will catch on and possibly cause real damage. People will rapidly lose trust in most sources of news, entrenching established known quantities.
I feel like if we could reasonably put a stop to this we should. I don't think we can in general, though.
