I'm not saying there aren't good use-cases for this. There absolutely are. What I'm saying is that this tool WILL be used well beyond those cases in ways that make the internet much worse than the ad and surveillance nonsense we currently have to deal with.

As a thought experiment, consider a truly terrible group of smart and capable people. The kind of people who will exploit this new tool to extract and squeeze every cent from others to themselves without any care for what is destroyed, broken, or ruined. Imagine they do exactly this and become wildly rich. Their uncaring ruthlessness richly rewarded leading to normalization of such tactics which are then taken on by others as just the 'way things are done'. I ask you to consider just how this tool could be used for evil and then know that it will be.

This tool will allow any/all action on a website to be easily monetized. This will mean that eventually EVERY action will be monetized. Oh, and the ads and surveillance? They'll be there too.
