Here's one: How successful was the combined efforts of politicians + 3-letter agencies + universities, at banning computer encryption in the past? Not successful at all, hahaha.
Let me explain a bit further:governments lost the battle to ban code. Since then, no code can really get banned. And, nowadays we have vetted p2p VPNs even if all world govs try to ban vpn companies, and no prism or quantum computing programs can bypass their post-quantum e2e implementation.
