I see where they are trying to go with the "humane" approach, but the examples seem to require big companies to play along. For example, the shopping examples put the control back with the user, and companies supply basic info like pictures, pricing, descriptions.
In real life, of course, they won't cede that control easily. You'll get the same sort of mess you see on Facebook Marketplace, for example..."for sale" listings of cars that put the down-payment in the sales price spot and some wording telling you to call for more info. No actual prices are shown.
So, it would probably require some sort of unapproved scraping, collating, etc, to really work as intended.
The web lost track after the dotcom. In the beginning there were protocols. Now we're in the corporate moat period, where N corporations build the same thing N times because each one of them wants to dominate the others. Consequently, we were left with low-level protocols and languages (http, html, css, etc); there is no standard for buying shit online, despite most businesses being online. No standard for payments, no standard for query/search/browsing, etc. Compare that with, e.g., computer graphics, where graphics vendors (except Apple) collaborate on the development of standards like OpenGL, Vulkan, OpenXR, and shit works relatively seamlessly modulo vendor bugs and extensions.
