To an individual taking pictures, the public is no great resource and can not be significantly used as a source of asymmetric power. An individual's "public" is a small sphere around them as far as an affordable camera can see.
To nation-states and large corporations, the "public" becomes virtually all of the spheres around every individual. It can be combined into a database which is no longer accessible to the individuals in the database, making it no longer public. It can then be used asymmetrically by the organizations against individuals. For example, mass-gathered public real estate information can be pitted against individual buyers and sellers of their homes. It biases the market toward those who can collect the most information using capital an individual with a single camera could never collect. In the case of google streetview, a monopoly has been formed.
When our country was formed, such asymmetric power was scarcely imaginable. We need to reconsider whether mass gathering of information should be allowed.
