But that argument is not limited to tracking, isn't it. For example if I use an application that integrates with Shopify or Stripe, by that logic Apple would also be in the right to ask for consent (while the integration with Apple Pay would be pop-up free). In fact I don't see any reason why Apple shouldn't go after those businesses next - there's a clear privacy angle they can play here too. As much as I like Apple Pay as a consumer, I don't think Apple should get a blanket pass on favoring its own infrastructure over any third-party integrations just because the user is less confused about their relationship with Apple.
