I don’t understand the relevance of that argument in this context.

Computers can cut ads that do tracking out of the page with the same effort they can cut out anything else from the page.

The difference is that ads without tracking remove the incentive for the user to block them. This is why people don’t cut ads out of the newspapers before reading. If the ads in newspapers were cameras, analogous to the tracking used in online advertising, you’d see people expend that effort. Just as you see people blocking ads online.

Plenty of people block ads because the ads themselves are annoying. People don’t cut ads out of paper newspapers because it’s more annoying to do that than it is to just ignore the ads.
