Andreas speaks about DAG. I think he is right that with DAG you sacrifice decentralization and coersion resistance by removing proof of work. Byteball is a good example of this. We have 12 witnesses in the hands of 1 person. And even if these 12 witnesses are 12 different people it's easy by governments to coerce them for censorship or just shut down the whole system.

Humans tend to be centralized in nature but still has a decentralizing aspect of their behavior. Just look at the US and its politics. The point is you have to be vigilant. Not everyone can be coerced.
