Proof-of-stake has much more ability to enact censorship resistance (https://blog.ethereum.org/2015/06/06/the-problem-of-censorsh...) than proof-of-work. PoW imposes huge entry barriers by restricting mining to those who can build and then operate expensive mining rigs, which are resources not equally available even to people with the same amount of money and may be monopolized (how many competitive mining rig manufacturers are there, and how many countries do they operate in?); PoS makes participating a much more level playing field by removing dependence on physical and monopolizable resources.
PoW does have sheer simplicity and a proven record of working on its side, but the idea that whatever upsides to PoW over PoS that exist are and will stay worth more than 0.5% of global electricity production seems extremely biased.
