And micropayments would've taken off in a big way.
The only reason why micropayments doesn't really exist today isn't due to technical reasons, it's because advertising is too dominant, and because consumers got trained on expecting everything on the internet to be "free", not realizing they're the product.
Humans are only now figuring out pointy shoes are bad for people's feet. This species is wrong about almost everything when it comes to its own well being and like pointy shoes - it's a completely unnecessary self-own that barely benefitted anyone.
I think advertising runs a little deeper into our identity and history than you are thinking. If you have a sign in your window describing your wares, that's advertising. If you're standing on a street corner inviting customers to enter, that's advertising. If you're doing nearly anything to make the world know that your business exists, you're advertising. I'd rather not live in a world where "ad cops" see fit to intrude and opine on such activities. Attacking PII brokers, on the other hand, would do far less collateral damage.
I'm with you on the shoes though.
Pedantry is not a counter argument, it's a deflection. We are not in court.
