Yep. Also this could be approached as an adversarial machine learning problem, analogous to a spam filter. Modern spam filters re pretty good, so if push comes to shove, I'm pretty confident adblockers will adapt to more creative ways to circumvent adblocking

If it leads to an arms race of adblockers vs. websites wanting to serve ads, the longer the race goes on, the longer web-page loading times become. So eventually a website will lose because its loading times will get too long and users, even non-adblocking ones, will go elsewhere
