If you care about privacy don't post private stuff online.
Saying "Lysenkoism is true" is factually wrong, but saying "physical possession is equivalent to ownership" is just a very fringe political opinion.
So I don't see how "the GDPR" can be wrong, unless you mean it in the sense of "the death penalty is (morally) wrong", which is just your opinion in that case.
My point is this: If your insurance provider, for example, obtains access to your medical records, and store them on their servers, does that make it "their data" to use as they please? This would imply that:

It is a fringe opinion in today's West, but only relatively recently: since the 1970s, one might argue. The fringe opinion, to be clear, is the older one implied to some degree by "possession is nine tenths of the law", and which views copyright and patent as an artificial grant from the State, useful, but not property in the same sense as a table or a knife is someone's property.

The fact that makes it your data is that you physically can share it with someone else.
At least that's the value system I live by and I believe should be in place for all because it perfectly reflects the reality of what happens with ones and zeroes.
Tangential but, if a nonhuman takes the photo, that makes it public domain, right? (In this case a monkey, or maybe in the case of a robot?)
Or is it different if there's a human in the photo?
