I appreciate your opinion and your position on the curve.
But, there are at least on the curve, two private keys that are completely different from each other. At the same time they form identical (identical)
Public key

The address is both compressed and uncompressed.
But, in my opinion, there are 4 such keys. Which can be different, and at the same time form the same source data, up to the address itself. (I can't prove the theory of 4 keys now, I'm working on it.)

P.S.
I can't prove the theory of 4 keys now, I'm working on it. In free time from work.
