Blocking ads wholesale is a terrible idea and unnecessary. What needs to be blocked is ads that execute client-side javascript (consuming your memory and cpu), ads that consume too much network bandwidth and so on. Ads are necessary so that content producers can generate income, without it they won't produce quality content. When you block abusive ads (as opposed to all ads), advertisers are encouraged to make their ads less abusive. Content producers get paid and you get to enjoy the content for free. Everyone wins.
