How many more sites are you willing to pay at that same level?
Right now, as far as I can tell, advertising supported sites are out-competing sites that directly charge users, meaning that users prefer not to pay. That makes leaves advertising as the most sustainable model.
Simple sites designed to promote the spread of genuinely useful information can be designed to use microscopic resources and operate on little money these will be fine.
Some sites provide neat services people are willing to pay for these will be fine.
Some sites represent the online presence of organizations with significant budgets these will be fine.
Much of what remains isn't worth much and if no viable means of support can be found I guess they shouldn't exist.
Honestly 1/2 of the modern web could go away and not much would be lost.
It's only a crisis if your livelihood depends on making a bunch of crap nobody in their right mind would pay significant resources to support.
Do you believe that's realistic?
What sites are so essential that we couldn't replace them?

Cuts both ways.
I'm sure that if a large number of companies were able to cut $277 from your average aggregate monthly spending in exchange for a guarantee that you were buying their products, they'd be signing up. Perhaps some sort of subscription service that you couldn't opt out of. You can try doing that as a startup.
