Developing PoS systems for 8 years, the research is completely dated on both old Bitcoin-like PoS and modern PoS. That, and the author has a wrong understanding of the Nothing at Stake problem. At the time, the argument was there was nothing stopping someone from staking on multiple forks to hedge their bet on the dominate chain, giving them nothing at stake on the forked branches since the get equal ownership on each chain. Mind you, Nakamoto consensus is pretty awful and completely ignored these days. Why do you believe that nodes flagged for support of protocols and miners with dominate hashrate LOST the big block debate? Because of the nodes, and community consensus.
