Now that YFI can be used to borrow DAI under Maker - the YFI in governance can be used to do that to juice up the yield for people staking ( whenever limit for YFi is increased - which i think will) apart from cashflow from Yearn network itself.
Mint DAI within limits in maker for the YFI in the staking vault
Use the YFI in the governance vault to get Dai under Maker - put it in the Dai strategy - Profit
For: Just Do it
Against: Stay Poor
