The benefits are a bit of a red herring here.

What you're proposing is that everyone should be subjected to spying because it may lead to some theoretical larger good. That argument also conveniently ignores the theoretical social and personal costs of that spying.

What I'm saying is that everyone has rights that include the right to not be spied on, and a theoretical larger good is not nearly a solid enough reason to strip me of rights.

Getting consent is a way to avoid this deadlock and make everyone happy as well as ensure that nobody get trampled.

Now, while I would never give Google consent for data collection from me, that's because I have zero trust in Google. However, if we're just talking about consent in the general sense, then it's certainly possible to make an argument that would get me to agree to share data. In fact, I do so with a few entities already.
