Using that analogy, all the 1s and 0s in your private key are the same as everyone else's as well. Genetic data can be used for all kinds of things, the worst of which would be things like targeted diseases or planting your DNA at a crime scene.

Actually it's like your private key is made up of ~1000 1 mb pieces that each have 1/1000 rate of difference with any other similar piece. Oh, and the order of the pieces is almost always exactly the same.

No, genomes are not "almost the same" because they are all in base-4 sequences and this made up of the same 0s 1s 2s and 3s.

We are astoundingly similar, even unusually so for a large mammalian species.
