Charging per page view would only work for pre-approved sites and have many of the downsides as ads, not sure I like that idea at all. Also micro-transactaions are not necessarily about payments like we are used to them now, but could completely transform how donations worked.

And also paying after the fact, did you like the content? Pay. Not have to wade through ads "paying" for something that turns out was only clickbait, tracking and garbage.
