If that worked, we would have already solved car accidents (obey all the traffic laws!), suicide (don't kill yourself!), obesity (don't eat too much unhealthy food), debt (don't spend more than you make), and basically every other social ill.
Effective solutions are ones that can be enacted by humans while fully taking human fallibility into account. It's poor engineering to design a system that requires every part to function perfectly with zero tolerances.
I think that's true of the general problem of data privacy, but I don't think it's exactly true of the particular "Facebook" instance of that problem.
Social networks have withered and died before, and there's no reason to think that Facebook can't be nudged in that direction, one user at a time, until the snowball starts. This seems like a pretty opportune time to get that ball rolling.
But as individuals, there is something we can do today: not use it. Why dismiss this very simple solution?

Which basically sounds to me like, "If every fallible human on Earth can't individually decide to solve this problem, they don't deserve any solution."
1) Even if you actively decide to deactivate or delete your account, nothing guarantees that Facebook won't retain the data. Nothing guarantees that they don't continue to build a profile of you by scanning photos your friends share. It's a Hotel California of personal data.
2) Even if you personally decide to leave, the rest of society may be using it for passing essential information that forces you to re-engate with facebook. Until you can convince your cohort to stop using FB to organize or converse, you might still be forced to use the service.
i still have an account for logins. i could technically make messages happen.
i don’t have to eject all my pictures, or delude myself about the efficacy of “deleting” my fb account, but i can be sure nobody is going to benefit from selling my social graph to my “friends” or frienemies
