Americans are too privacy focused to accept this, but I could easily see a cottage industry of "registered agents" popping up around it who sign leases on behalf of individuals and shield them from public scrutiny.

Alternatively we could keep the names private. A cryptographic solution would easily serve the need of authorities verifying the right person is in a place without identification, but good luck figuring out how to ensure the tenant has their keys somehow since in the US there are zero pieces of identification you can ensure every citizen has.

Are we privacy focused? Look at products like Facebook Muse, or Facebook, or Instagram, or Whatsapp, or the perv glasses, or or or

See RealID for how long certain states has been kicking that bucket down the road.

American's seem to only care about privacy from the government, but wanting privacy from trillion dollar corporations? They keep the stock market high and provide value to their major investors and everyone's retirement accounts so obviously its fully within their rights to spy on us 24/7. /s

Well, a Torrens registry systems still isn't universal yet in the US.

Berlin wants to do that to enforce rent control more effectively.

I think publishing your own rental contract is already legal?

(Unless the other party to the contract deliberately asks you in the contract to keep it quiet. But that's something you need to actively agree to.)

It’s more credible if it’s in a government database like property sales are, plus there would be a lot more pricing data.

Governments ain't magic.

Abundance of pricing data depends on whether you make the registration mandatory more than who runs the database.
