How would you formulate such a law? What does Germany's Telemedia Act actually say?

I can refuse to let you into my house if you won't show me your passport. If you don't have a passport, then I can just refuse to let you in no matter what. How does that change if I'm running a business? Or a web-site?

Well they basically say "It's illegal to ask for and store personal information like that". "Fine", you say, "I'll just deny you access unless you do this and that". "Fine", they say, "We'll see you in court".

It's like anti-discrimination law. Sure you're free to run a business, but there are legal limits to what you can do.
