As I see it - all ads doesn't have to go. Ads that are sensible (static images and a short catching message) and only a few of them per page will provide less incentive for AdBlock softwares.
The big thing here is that once you go AdBlock you rarely go back. Sites that denies access to AdBlocked clients will just get less visitors unless they have a very sharp edge and are unique that makes people willing to disable the AdBlock function for that site.
News sites with paywalls - well, it start to look like that more news sites have paywalls, but that just leads to shorter visit times and just reading the headlines - which may result in misinformed readers instead.
