I am no longer convinced that even that is enough when the relationship is not even close to symmetric. Network effects, psychological manipulation via ads, sunk cost fallacies, bait and switch etc. all mean that companies have so many options to pressure users to agree to terms that they don't really want to. Yes, if everyone acted rationally that wouldn't work. But people are not rational beings. And you certainly don't can't make others whose choices influency you act rationally.

So ultimately when it comes to company-user relationships nothing short of making some rights including privacy inalienable will prevent this shit. That's why we need laws like the GDPR and similar ones in other regions. Because corporations have shown again and again that if there is a profit to be made of abusing users they will find a way to get away with it.
