If you click on 0 ads per year, you generate $0 for Facebook and therefore your data is worth $0.
For a personally targeted (using your data) ad click on FB, you're looking at ~$3.25. For a web targeted ad click on a niche website, you're probably looking $0.50-$2.50.
In other words, your "data" is worth $0.75-$2.75 per click of revenue
FB spends 17% of revenue on direct costs and another 18% on marketing. Let's ignore R&D improvements and assume 35% of costs to serve that revenue.
Profit per click for FB = $0.49-$1.79 per click.
Please consider that these clicks must have real intent behind them. In other words, there should be at least 10% chance you'd actually buy that product.
In other words, your data is not worth that much money.

On the flip side, FB should offer a paid ad-free version of their services but who honestly would pay $10/mo for FB + Instagram etc.?
