If the ad-blocking crusaders succeed in eliminating all discrete advertising from the web, then what we're left with is (1) very little content (2) lots of paywalls and/or (3) a web supported by paid placement. If users don't allow the ads alongside the content, then the ads will become the content. On the other hand, if you choose to block ads and recognize that your decision to block ads and enjoy the web as it exists today wouldn't be sustainable if everyone did it; just accept that you're freeloading and move on.
