How come this is a complete non-concern in other areas?

If you give anyone (say, PayPal) your address, you’ve given then your roommates’ address as well - since you share the same IP. Nobody cares, even though the third party can immediately begin identifying your roommates without harvesting their DNA, like they would in the case of 23andme.

Giving your address to paypal doesn’t give paypal the addresses of everyone out to 3rd cousins (i.e. related via your great grandparents).

There’s a slight difference.

Giving your address does not give the address of your roommates. They also need the list of your roommates to conclude the address of your roommates.

Given that I know the mapping of an IP address and a physical address, I am unable to match one to the other?

I suspect you’re attacking a strawman.

Having the same IP address doesn't imply people are roommates. They might be coworkers, classmates, sharing Internet service, using the same VPN, etc.

It is easy to move. You can't change your DNA.
