I think this would be a net benefit, but I can see an issue. A lot of news sites today do "accept tracking, or pay us, or you can't access the page". The orgs doing this are reputable-ish so I assume it's considered legal, on some level at least.

So now they'd have a new popup that says "reconfigure your browser to accept tracking, or pay us, or you can't access the page". Which isn't really an improvement.

"accept tracking or pay" has already been ruled against, it just hasn't been universally enforced yet because enforcement takes time.
