I didn't plan to intentivise anything, just proposing some solution for this dilemma :
Unfortunately, where it gets stuck is that the math never works out in a way that is feasible. It either doesn't offer sufficient rewards for it to be "worth it" for investors to be passive, or it takes way too much of the rewards away from the active users in order to pay for the program.
If everyone loves all their stake to passive, we have a much bigger problem. The whole concept of rewarding good content would be wishful thinking then. I don't believe it is.
If everyone loves all their stake to passive- but you don't - then, under my proposal, you alone will distribute 50% of the current reward pool.
Which is a bad thing, because maximizers will switch their stake back and forth depending on profitability, and we wouldn't solve a single current issue.
