There is, but I think all they'd have to do to get money is ask nicely. I have high hopes for Patreon as a platform for that. They could also ask nicely to whitelist the site in ad blocker, promising they won't abuse it. I've seen a site that does that and happily complied because hey, I get it, they need the money and I do get some value from their services.
The reason people block ads is not because they don't want publishers to get paid. It's because most ads are actively user-hostile, ranging from merely fucking annoying to malware vectors which can cost you a lot of money. Quoting 'jacquesm from other subthread, "Browsing the web without an adblocker is like sex with multiple partners every day without a condom.". [0].
