I'm in agreement with you that most computer users haven't bothered to learn anything about how to use their browser or computer. But still, let's say I agree that there's even an important problem to be solved. We can (A) regulate the browser to dumb this down for these ignorant people, and have the problem guaranteed solved, or (B) we can burden every single company that operates a website, and rely on enforcement since otherwise it's all honor-system. The EU and so far multiple US states, have chosen the stupid option B.
