There've been several projects that did exactly that. Like Brave with their BAT tokens. But it never took off.
Personally I don't like them because these things don't normally opt you out of ad tracking as well. When I pay I want to be the customer and not be tracked. I also don't want to give any personal details. They know nothing about me when I buy a newspaper in the shop. It should be like this :)
Yeah, this is sort of a deal breaker. Another response to my original comment was a link to Flattr and from wikipedia it's a site "that records which websites they frequent and shares this data with Flattr" -- no thanks.
Not Brave itself, but the sites that you visit don't have to give up tracking per se (for participating users, of course). They should have to in order to participate IMO.
Brave will block tracking to some extent but we know it's not perfect.
