You will never see 51% approval due to apathy, lost stake, etc.
I am trying to understand your position. Do you have a philosophical objection to a proposal system ratified by shareholder vote? Or is it just that you think the added code complexity is not worth the development time for the benefits (if you believe there are any benefits) it provides?
Keep in mind, the proposal system is far more general than how much inflation trusted actors get to create and spend to improve the DAC. It allows shareholders to modify parameters that govern the DAC: imagine adjusting interest rate caps on BitAssets, or minimum collateral reserve requirements, or even the number of active delegates. It allows shareholders to decide when/if to upgrade features in the DAC that require a hard fork. Currently that is done by the core developers telling the delegates to upgrade and the delegates following orders. That is centralization. That is okay in these early stages, but I am trying to future-proof this design so we can eventually transition to more decentralization.
That said, even though I am still a huge supporter of delegate proposals ratified by shareholder vote, I realize that maybe it is not the right time to try to get an implementation of this proposal ready for DACs like Music, Vote, and DNS. I don't know how much development time it would take to implement and I don't think it is that important currently to take away precious time that can be spent on more important features and of course killing bugs and improving BitShares X. So further discussion about the proposal system is a hypothetical discussion about the potential benefits of a feature on my wishlist, but one I still really wish to have, time permitting.
