Or, ya know, just issue people a government digital ID?
We could just play catch-up to Estonia and issue people a modern digital ID. We're talking about a few hundred million records, so it's not like we'd be building a massive piece of infrastructure here. It might take a bit to fill it up, but it would be a great excuse to fix the RealID fiasco at the same time.
People already have IDs and accounts at the state level, in the passport database, and social security, so it's not like this is a green field deployment either. Not a trivial undertaking either, but with a federated ID provider a bunch of problems, including more accurate survey data and direct democracy efforts like the one mentioned in the article become very reachable. Tough to face a RfC post when you have to crack a MfA token, and the owner gets a push notification their account signed into the FCC portal while they were on the can.
This won't fix access or equity issues, but it's a start, and a glaringly missing piece of the puzzle at present. Instead we let lobbyists from, you guessed it, Facebook and Google block efforts to do so in the hope they could provide (and control) those services themselves.
