This is the most convincing argument for me. Despite the risks, I know these sorts of anonymous confirmation systems already exist.

Most VPN services tout “zero logs”, and many back it up with audits. We can demand the same from our government.

I’m sure drivers licenses and social security numbers made people uncomfortable too when they were rolled out, but they certainly improved our lives.

A slippery slope is a logical fallacy - we can impose just enough oversight to be helpful AND curtail overreach.
