There is no part of this that I disagree with. I think it might be difficult to get the needed percentage to vote.
If it is not possible to pass this proposal I think the suggestions @bitcoinflood mentions in the comments should be explored- I would prefer adding downvote costs to the downvoter over removing it completely.
By all means, if this proposal is rejected, suitable alternatives need to be evaluated as well. @bitcoinflood offered up some excellent suggestions.
For that matter, even if this proposal is ratified, subsequent proposals to tweak the settings and/or fill in the gaps will likely be needed.
