That's part of the problem - opt-in never works because it's an inherently an anti-consumer practice. The industry got so used to vacuuming up as much data as possible that the moment you give customers the option, they do not want to partake.

You know it's a bad thing when you say "If I ask users for consent, nobody will agree to this."

I as a customer want full control of my data and if you, the website owner, try to force me into giving data that I did not consent to (invasive site analytics, for example, that track my page behavior), I will go out of my way to block that through extensions and by just banning things at the DNS level.
