You don't 'need' tracking for ads, but it has a huge impact on the the amount of revenue per impression the ads will generate, because tracking enables you to show ads to the people those ads are relevant to.

There are a lot of business models that are feasible with tracking for ads, but are not feasible to offer for free without tracking.

Anyways the whole discussion is moot, tracking of users is illegal. Im sure slavery versus freedom of employment also has a huge impact on the amount of revenue a farm might have. Protections and regulations are usually created for a reason.
