People keep repeating this defeatist drivel but it's just not true. It's still up in the air whether you can defeat a law using technical measures, but it is a thoroughly settled matter that you cannot legislate away mathematics.
We saw how laws completely failed to make encryption illegal in the 90s as open source encryption code spread rapidly on the internet. "Exporting" encryption software was illegal in many countries like USA and France but it became impossible to enforce those laws. A technical measure defeated the law.
Encryption is just maths. It is the law being unreasonable here, and it will be the law which will ultimately have to concede defeat. UK is the perfect example here - Online Safety Act's anti-E2EE clauses have been basically declared by Ofcom to be impossible to implement and they are not even trying anymore.
