PoS is not as decentralized as PoW. With PoW, you can literally transform energy into cash. In order to be part of a PoS network, then you need to buy the token/coin first. What if you are in a country that restricts crypto? How can you participate in the network? The whole point of using blockchain is to make something truly decentralized. If you are sacrificing decentralization, then you should ask yourself whether you are using the proper data structure for the problem that you are solving.
