What "extreme benefits" do I derive from being filmed and analyzed by stores I happen to walk past?

this is already happening and it's already providing value.

What does a filmed image give you that isn't reflected by sales numbers?

The goal of tracking isn't to make and sell better products, the goal is to create an environment in which the product you already got gets sold more. So essientially people who track you want to manipulate you into buying shit you don't need at prices you wouldn't pay unless manipulated.

Tracking people who would buy your product anyways isn't all that interesting: you've already got them.

since on street analytics are already beneficial to everyone, consumers and providers, why should they be opt-in? they should be, and currently are, automatic opt-in with an option to opt-out. you are walking on the street, so any privacy is gone just from walking outside of your home.

And I hope this:

is a joke. It's pure authoritarianism.
