When it comes to distributed/local technologies, does a ban really accomplish anything? I'm dubious that facial recognition technology will disappear because some random governments passed laws against it. Especially because it's nearly impossible to punish when police can just use parallel construction. "We received an anonymous tip and followed it up."

The solution instead might be the same with deepfakes: fill everything with junk data.
