Strongest arguments against self-referentiality in PoS

Why Ouroboros Chronos and Proof-of-History need synchronization of time?

Having an internal clock greatly reduces the overhead for block propagation, as it would allow for a more forward, almost "UDP"-like, block stream. Nodes are then able to order blocks ...
