I could perfectly think of a scenario where there is an anonymously deployed "faucet" contract with some logic that distributes its coins to various L2 protocols or maybe some form of future shards, and enables people to interact with that contract's currency on those upper protocols whereas anyone can claim those coins by only paying gas. And anyone could participate anonymously by doing a little mining over VPN/Tor in a pool with a freshly generated wallet for a little Ether that can be used for gas, and again submit their transactions containing any speech they like using again VPN/Tor and not interacting with those wallets with any KYC-enabled exchange. Sure, gas fees aren't that low to cover with "a little mining" but I'm sure there will be a middle ground between with more gas available for anonymous posting and optimizing gas use for these actions, with some volunteers over the world incentivizing free speech contract interaction with lower gas fees just like people volunteering to participate in Tor network. While we're not there yet, I see it very hard to trace any transactions that way.

> again submit their transactions containing any speech they like using again VPN/Tor and not interacting with those wallets with any KYC-enabled exchange. That last part seems like the key challenge to me: what you described isn't cheap and it only works to the extent that you can do business with people who aren't following KYC. That makes it more likely that the entire service will be tainted because the non-trivial cost means that people aren't going to use it if they don't need to. The other problem is that durable records are inherently risky. Your use of such a system isn't just a question of whether someone can see the transactions immediately but whether it'll retroactively become de-anonymized — the public blockchains are right out there but if you're trying to use a private L2 system you now have another party you're placing a lot of trust in — not unlike the questions about how you'd be able to trust a VPN provider or Tor nodes not logging your traffic.
