You can jail a person but the contract or message they deployed, which may include private encrypted information or even be a fully fledged blockchain application, is still accessible and functioning as it was before. That is the point of the ledger being censorship-resistant, and it’s a different model than trusting a small handful of node operators.

PoW and PoS may rely on speculative valuation of the token but they aren’t really like PoA at all. The whole concept is that they are permissionless, as opposed to permissioned.

But anyways we have three options: PoW, PoS, PoA. And there are crypto currencies and blockchains for each of those. PoA tends to secure the least amount of value as it’s generally seen as less secure, less censorship-resistant, and less distributed.
