It's not really as clear-cut as that. And if you read my original post you'll see that I did say I couldn't see how that would work in practice.
What I was questioning was whether a method could be found so that content-providers would end up still managing to stay in business despite their revenue-stream being removed by ad-blockers. Since ad-blocking is a service that some people clearly want, and since using ad-blockers deprives other people of a source of income (the people who make the content you want to see), it seems to me that if ad-blocking were a paid service and some of that payment filtered through to the content providers, then the problem would be somewhat redressed.
Of course a better model would be for a secure micropayment system to be available, so that content providers could choose whether to monetise their content using ads or direct payment. And the customers could choose whether to view ads or pay a tiny amount to avoid them, with the warm feeling of satisfaction that they were no longer depriving someone of their livelihood.
Putting ads on a site is not something that web authors *like* to do - they want to get their own content seen, not have you distracted by someone else's ads - but it is currently pretty much the only way to make any kind of business out of providing general web content. Just hosting a website costs money, let alone developing it, and the cost has to be covered somehow.
The truth is that advertising pays for content, and if everybody blocked ads then the vast majority of the web would become unsustainable. Including, I suspect, this site.
