Many things are fundamentally feasible. I see 2 things you argue for.
One is changing the caching strategy. I don’t think that’s wise in terms of load sharing, but certainly feasible on a small scale. In certain circumstances, it may be preferred.
The other thing is using older protocols and standards. The practical reason to do this would be to use existing tooling, libraries, code. I’m not seeing such opportunities. I’m not that familiar with these, but it seems like they would have to be extended anyway. So I don’t really see the point.
It’s happening all over Europe and the US, but especially Europe. Police were used to being able to eavesdrop on any sort of communication. This becomes ever less possible, while at the same time, you have more and more crimes that are committed solely by communicating and can’t be prosecuted or even detected without massive internet surveillance. I think the US commitment to “free speech”, freedom of information, has a somewhat protective effect.
Of course, these online-only crimes are 99%+ copyright, but even copyright has gained in favor among netizens. Then you have “deep fakes”. Bunch of other stuff like holocaust denial. Going after such stuff is quite popular among lemmings, too. And how else are you going to enforce all that?
