Sorry, I should have been more clear. I think this is an important (larger) point because we don't need to pretend that this move would completely upend the ad industry. It will just slightly change it, and revert it to how it worked for the hundreds of years that preceded ~2005. I think ceding the argument that this change "breaks" advertising is the wrong move. I think it's important to keep focus of what we do want to break: the sleazy practice of tracking individuals so that they can be targeted for specific ads. That's gross, and absolutely deserves to go away. Publishers can continue to be supported by advertisements. There are tons of mailing lists that already work this way, and several very popular websites (e.g., Daring Fireball)
