The day the usual website will receive 12 to 20Billions views a month and occupy 10TB of disk space, then we could use wikipedia as a representative example. Until then wikipedia should not be used as an example of how well the usual ad-supported website would fare with an alternative revenue model.
IINM wikipedia has chosen a business model not based on ads which successfully funds the project for about 10+ years.
Yes, that was my point — Wikipedia is probably the absolute best-case scenario for a free website that isn't supported by ads, and they're still panhandling. The usual ad-supported website would fare much, much worse, and would probably just stop providing its service to the world.

Some have already transitioned to crowdfunding (see patreon, the dice tower getting funded on kickstarter,...) micropayment, subscriptions.
But this case of "your failed business model is not my problem" is not to blame on adblockers alone but also on dwindling ads revenue among others reasons due to facebook driving prices down. When facebook investor story time will come to an end the whole web advertising ecosystem might crumble on itself.
