The oracles don't have the power to completely run everything. With the current split for rewards, 25% of new coins is from just staking. As well, because new blocks are made only proof of stake, a 51% type attack would be also be much tougher for the oracles conspire and to pull off. Even if they tried to redirect 100% of research rewards (28750 GRC/day) to one address, it would take over 900 days to even reach the same amount as the address with the largest balance (~6% of current coin supply) [1]. Further, there's also more resiliency. If the oracles somehow broke or conspired and all said everyone did zero work, the network would still run. Now granted it would not be great that only previously pending research and PoS rewards would be given out, but you could still send coins, run polls, etc. [1] https://main.gridcoinstats.eu/address/ https://main.gridcoinstats.eu/address/ (excluding the very largest one (the foundation) because it's multisig and can't stake. In its case it would take 1000 days to reach)
