So the government would limit me to accessing only 999 porn sites a day?

Is it going to be like structuring law, where it's illegal to access 1000 or more but it's also illegal to avoid accessing 1000 or more by accessing a lower number?

The government won't limit you - they can't really know what you use those proofs for anyways, that's the zero knowledge part, and supposedly they'll be necessary for social media at some point, so a ZK proof won't necessarily mean porn use. The only thing the govt knows is how many proofs are being downloaded. And you can bet politicians wouldn't do anything to prevent voting-age you from accessing social media - how else are they supposed to get you to vote for them (or hate their opponents).

Now, a scenario I can see happening is, the ZKP-issuing agency may find a single client downloading several orders of magnitude more proofs than the average citizen, find that suspicious, refer them to the police, who'd get a warrant to investigate said person. Then, the police may manage to connect said person with a proof distribution service. Something along those lines.

Again, I'm personally not a huge fan of the whole age gating, but if we're going to go about it, this is the least worse option. Which is really saying something.

How many proofs will be illegal to download? Will downloading and discarding proofs in an infinite loop be a crime?
