For floss operating systems someone will inevitably maintain a (potentially illegal) fork/patch that bypasses the age check. The same will be true for repos and flathub, there will be a mirror without verification for most stuff. Just like youtube hasn’t been able to smash yt-dlp yet I imagine that there will be bypasses that fake an “adult token” to send to websites. What we can do is: a) Join organizations, eff.org exists and maybe your country has a local organization too? b) Discuss privacy with friends, we all have things we’d rather keep hidden - a medical journal, a hobby most find childish or a kinky sex toy. That doesn’t make us criminal. Encourage them to accept newsletters from eff and similar groups. c) Question your politicians about their view on privacy, we must make noise for them to care. d) Submit letters to your local newspaper in regards to privacy. If they publish it that’s a win and if they don’t then maybe you got a journalist interested enough to write a full article. Someday. e) Join politics and work inside the system to protect privacy for everyone. f) Go offline. Host get-togethers in real life, create regular groups that meet outside the internet, read books, play tabletop games. g) Become a hermit, plant potatoes, feed the birds. Live far away from town.
