That's why (for now and in this case) apps win. You get to make money from ads, and some people pay you a dollar to remove those ads.
No, that approach hasn't worked well either. See for instance the failure of Newsstand, which had the benefit of being a marquee iOS feature featured in a keynote. People want free and no-strings-attached.
If there was a truly low friction way to get a single piece of vetted/high quality content for a marginal one time rate (the sort of thing I used to hear from a lot of the bitcoin crowd as a potential use case, but only saw materialize in partial forms via things like dogecoin) I'd be much more likely to do so. (or if you're feeling generous as a content author, a low friction way of donating post-factum; the "paypal button" (and similar) is not a great solution as is due to aformentioned high friction)
tl;dr, it's still neither common nor easy to be able to transfer small sums for specific content. This is a model I'd support over both ads and current-form paywalls.
This post had too many qualifiers, which I think indicates it's clearly not cut and dry, but I worry that to paint a broad brush of "nobody wants to pay" distracts from finding a model that will work better.
