The options are ads, pay, or public funding. Public funding is obviously the best option in many cases. For example, non-profit basic internet services

I think the pay solution could potentially work. The biggest issue is the decentralized nature of the internet. If I could setup an account which gives me access to everything ad free, but deducts what the page would earn in advertisement (say something like $0.001 for a visit) and most of the internet which does a pay wall participated in this scheme, then I'd do it. I'd happily put in $10 to such an account and recharge it when I start finding the internet being locked away.

You'd want such a platform to be relatively open to allow anyone to participate, but you'd also have to be pretty aggressive at policing as bad actors would be all over the place trying to artificially drain an account. Maybe it's something that could be built into the browser? You could get a "X would like to charge you for a visit" which you could approve or deny and you could configure to always approve.

Transaction fees would be a beast.
