I addressed that above. If that's the point, the people with disposable income who view the ad subsidise the ad broker and the website as a hidden charge on a product which they probably didn't need. It doesn't get less efficient than that. I'd rather that people living under the poverty threshold get subsidised directly

Advertisers/brokers will also do everything to optimise to whom the ad is being shown to not waste they money. Poor people can't turn it into arbitrary cash, they can just waste time on video sites and freemium games while they barely (or don't) have enough money to make ends meet

I guess I am very much in the "let's pay fair and square" corner, both for websites/services and for taxes/subsidies where needed. I don't see it working reliably or efficiently any other way in the long run
