The constant angular field of view is the disagreement. A camera in the mid-gigapixel to low-terapixel range could cover one city by using an appropriate lens at an arbitrary distance (including space).
Any sensor finer than that would either cover substantial amounts of “boring” area (e.g. nature preserves, agricultural areas), or increase the resolution beyond your target.
I am still not clear where we are disagreeing, sorry.
What do you think is the bottleneck to building a petapixel camera that lets you do facial recognition from outside national borders? I don’t think you can simply stitch a bunch of gigapixel cameras together and achieve this.
A camera that can do facial recognition from outside of national borders doesn’t need to be a petapixel one. A mid-gigapixel camera with good optics can cover an entire city at once (or at least it could if it wasn’t for all the buildings in the way).
The main barrier to petapixel cameras is that they don’t serve your goal of full public monitoring (regardless of whether it’s by the government or by everyone individually).

This is technically true. But yes, if you had the tech to build this it would also become trivial to built a petapixel camera too (for someone who can afford it). The hard part is doing 0.1 metre resolution from a 10,000 kilometre.
Thanks for this exchange btw, I guess in future I could be more precise.

Why?
Assume we had the tech to manufacture petapixel cameras, and individuals worldwide could purchase them (i.e. a govt couldn’t just lock down the supply chain). Why does this not eventually to a world with zero privacy for everyone?
