I think methods of opting in and out of such data collection and use are essential. Also ways to compartmentalize and associate / dissociate identity from the data under the cryptographically secured control of the individual.
High sounding hopes, not sure exactly if / how such can be done, but reading about such applications surely concerns me.

"I think methods of opting in and out of such data collection and use are essential."
I agree. Sadly I can't see this happening though.
There are methods, alright... They may not be easy, however.
For example, I know some folk who wear Old West-style bandanas over their faces when out in public. Bright infrared LED collars are also reputed to help...
Granted, few will adopt such extreme measures.
