I remember complaining on Amazon about the price of digital books when they were still relatively new. They wanted me to pay the same price for a digital book as a physical book. Back then, Amazon still had pretty decent customer service and wrote me back saying that the price for the book wasn't for literal pages but for the work in making the book, etc. etc.
I told them I understood that but I don't get the same rights with the digital book as I did with the physical, namely the right to sell the book.
Books, board games, etc. any physical media is technically a license, yes. BUT the copyright holder cannot bar you from doing whatever you want with the physical copy, within the limits of copyright law. Those same rights simply do not exist with your digital copies and, in fact, is often codified within your terms of service that you don't fucking own anything and they can pull your license at any time.
DVD is next to impossible to revoke while Blu-ray is not. But you can't revoke Blu-ray licenses to specific people but to regions. I haven't heard of this happening but if it did, you could, in theory, still play your Blu-ray disks on players that aren't connected to the internet to receive those updates. That said, I'm like 80% sure that Blu-ray keys have been leaked and you can rip them like DVDs today.
Cloudflare sort of provides this now by being a MITM to secure your site between your server and the end user. But this requires you and your end user to trust Cloudflare.
And fwiw the ACME protocol is open so anyone can implement it. I believe even the ACME software that EFF sends out allows you to choose your server with some configuration.
