No; this is factually wrong.

And not even a bit of clarifying? If you can convert the DNA sample into two DNA copies without destroying the sample, probably you are a God.

You said "The DNA we are leaking is impossible to copy unlike the DNA we are sending to 23andme."

I said it was wrong because if people collect environmental human DNA samples and "copy" them (amplify with PCR).

Not sure what you mean about destroying the sample- you typically take part of the sample and amplify it without destroying the whole thing.

I'm just unsure of what you are trying to say here; I'm responding with purely factual answers based on modern DNA technology.

Nanpore sequencing can be done with a device that can fit into your pocket, these devices can be found for less than $1000.

You know, you can send other peoples DNA to sequencing services too…

Probably you can send to them anything else but how it relates to my comment?

Meaning that your DNA is not safe, even if you yourself never send it. DNA is leaking everywhere, anyone could collect it and send for analysis.

Why do you care again?

It's DNA, not your BitWarden password.
