Isn't the BAT/Brave concept a response to what is essentially the same problem as email spam? That is, unwanted/irrelevant advertising at near-zero cost to prod

Isn't the BAT/Brave concept a response to what is essentially the same problem as email spam? That is, unwanted/irrelevant advertising at near-zero cost to produce, and that increasingly relies on brute force to overcome countermeasures? If so, it might be worth evaluating it in terms of the myriads of email spam solutions that have been proposed over the years. Specifically, those solutions based on users adopting different client/server platforms and digital money. Both of which have been shown to be next to impossible to get ordinary people to do as part of their already-established use of the Internet. The general public barely knows what a browser is, much less the concepts involved in a weird new payment system.
