Heck, Linus Torvalds should just add an amendment to the next release of the Linux Kernel that makes it illegal to use in any jurisdiction that requires age verification laws.
This would obviously cause such a massive disruption (especially in California) that the age laws would have to be rolled back immediately.
This seems like a no-brainer to me but I am admittedly ignorant on this situation. I'm sure there's a good reason why this isn't happening if anyone cares to explain.
