I'm not sure this is realistic in our modern society. Online, there is some flexibility: you can pay to remove ads for some things, and use ad-block on the ones that don't provide such an option. But in the offline world, I'm not sure what you're going to do. Physical ads are hard to block, you just have to avoid them when you can. Economically, I'm not sure we're ever going to get away from ads. As I've said before in some of my comments, it's not just about paying for things you use. It's about paying more than the people who are willing to put up with ads, because otherwise companies will just do both: charge, and use ads. That's what we see in TV, in addition to many other places, and there's no reason to expect that not to continue unless there were widespread backlash, and I just don't see that happening. I don't like ads, but most of my friends don't seem to see things the way I do.
