With the ramping up of 18+ verification in Australia and now Europe (and South Korea and China already having such a programme for many years, including game time locks for young people), yeah.

It doesn't seem that big a leap to connect the dots from device attestation > web browser integrity > identity verification > verified web access

There is actually a relatively old game series of the 2000s called Bluesky Hacker Replay that has this as the core element of its worldbuilding. Governments and corporations became tired of the internet being overrun with spam, viruses, porn and cyberterrorism and decide to create an internet 2.0, tightly controlled by corporate interests. Hackers persist on the old 1.0 internet called the SwitchNet.

And really, when you think about it.. if you composed an internet solely from the big name social media, entertainment, work, food, news and knowledge services, running atop Cloudflare who verifies everyone via government ID, how many would really complain? 99% of their internet time is already spent inside that bubble.
