Nostr needs an ad mechanism that pays individuals directly for when they view an ad. With the ability to turn it on or off.

This way, people who have no funds, can receive payment for their time and attention to ad’s - something advertisers want and need to pay for.

In return, users can afford to pay for reliable relay access.

Which means, there needs to be a mechanism built into the web of trust that toggles on and off advertisements that are paying.
