I definitely agree with you on that part. To keep it simple, if you spend you time and energy doing something I say you earned it. (work = energy / time) so if you are spending your energy over time watching an ad or "selling" your medical records that you've generated, then you've earned the profits up to its worth. I think that is the beauty of crypto and blockchain like you mentioned in your post. Up until now people were not paid for all the things they "unknowingly sold", but big companies would and profited billions i.e. Facebook, insurance companies, media conglomerates etc.

Take for example: "allowing someone to use your medical records....or record where you are driving....or what you watch...or token you receive for listening to the radio..... or even watching an advertisement." You can share in the profits for almost every aspect where you spend your time/every; that is just beautiful.
