More intrusive? Could you cite examples? There is a business model that would afford the sites that are valuable to users to continue being operational: charging people. If ads can be circumvented, as we know they can, and your site relies on ads, maybe you should charge people outright for your content. If you can't make money by charging people, who cares if your site goes down but you? The value of a site cannot be determined by the operator of it. Only the users determine the value.
