Free market competition at what cost? If the entry barriers to be a block producer or staker are too high of the order of 10 million dollars, there will be hardly anyone to step in the role. Same thing as how much it costs to set up a political party, do political campaigns to contest in an election. I believe you should decentralize this thing in a way that there is a loose connection across the different resource providers and the different resource providers be basically plug and play candidates and give the individual stake/token holders a far more libertarian economy to work with. A light client working on a home computer or game pc with resources like ram, processor power/hashing power, disk storage outsourced from different vendors like Amazon and ipfs would be a far better approach to decentralization. That will make EOS more truly democratic. We do not want a few oligarchs only controlling the block production.. Again, voter apathy should be a big concern and people with high status quo cannot be easily shaken by the tiny stakeholders. It takes a lot of effort and communications to make different propositions and get them passed through and voted upon.. just my 2cents @Dan
