Could you re-phrase that?
Someone with 2 STEEM may very well be as concerned, if not more concerned, about its value dropping than someone with 1 million STEEM. Pushing all of the influence over rewards to the latter an then relying on them having 'more to lose' from the value of STEEM decreasing is nonsense that does not work, both in theory and in practice.
There is no incentive of good stewardship that scales with the size of stake, as the whitepaper suggests (as do you). It's a false model.
