NAT is still a major issue when you try to self host anything. And most of the stuff you can hobble together in a shell one liner just ends up being broken or limited in one way or another, e.g. that `python3 -m http.server` fails with seeking in video files, just gives "Broke pipe" error. Also provides no way to encrypt or authenticate. And without any way to easily mirror the content it will be unreliable and slow anyway.

Trying to do almost any common task is a nightmare when you want to do it cloud-free. An open web run by users themselves is still an unsolved problem. There some projects working on it (libp2p, IPFS, etc.), but none of that is to the point where it works properly and often missing important features.

That already happened years ago. Tons of popular Internet apps only exist as mobile apps with little or no Web interface. Worse yet, most of those apps are driven by user created content. Which is exactly why making publishing a first class citizen on the Web is so important, without that people are just leaving the Web and going to places that allow them to publish and those places will be controlled by your favorite mega-corp.
