Not in the sense that a couple rocks from the same pile are almost indistinguishable, but in a more fundamental level where physical characteristics between two or more of the same objects are completely indistinguishable to us. Lets say a "proton" just to pick something.

All protons share many physical characteristics, but regardless of the frame of reference you observe them from, their position in the universe is unique. At every instant of time each proton has a position relationship with the rest of protons that is unique.

Would you consider the position of protons in the universe relevant to its set of characteristics, (in an extrinsic way, assuming that if you changed the location of every proton in the universe, the universe would change accordingly), or would you say a proton's identity is intrinsic and nothing that happens around it is relevant to its set of characteristics.
