As much as this technology is powerful, you can't make it "illegal" to take photos of a public park, and then bring them home and do whatever you want with them at home. That would just be absurd. Banning the software online only isn't really an option, because the knowledge on how the software works is already public. Anyone could rewrite the code on their own (Esp because 300 line neural nets, no libraries used, are still pretty dam good at facial recognition). The real privacy should absolutely be on the data side. There should not be public databases of profiles. If you have a big insta profile or you are a big youtuber, then yeah, you'll be public even through you're not a celebrity. That was choice. Random people should be private. No mugshots should be freely available, and photos of social media profiles should be obscured by default. Or, alternatively, we accept that this is the way things are.
