That's called "quantified self".

I wish there was a systematically way to do that. I'd be the first to opt-in.

Privacy is overrated. It does more harm than good. Transparency is clearly the way forward, and what we'll lean from large-scale quantified-self will show that.

I'm confident that the model will soon switch from companies paying users (usually with services) to collect their data, to users paying companies to collect their data.

That's a very interesting expectation! What makes you confident in that?
