Thank you, great explanation!
This also includes trusting that this person is giving you correct proof, so there will need to be some form of degov involved in selecting the trusted validators. So you almost get a dpos scheme right there as you're ordinary eth goer isnt going to be doing zk rollups themselves.
Exactly, that's my point, you still need another layer of consensus, so ZK rollups are not really that magical solution that has no compromise. The consensus is not as secure or decentralized as ETH itself, it has the same disadvantages as other Layer 2s
