Thank you for your thoughts.
Advertising today is all about gaining maximum efficiency for ad spend. ie down to the cost-per-view/click. Buying half the platforms steempower could be a strategic move but very difficult to put exact value on and hence why most professional or major advertisers would prefer to buy eyeballs through mechanics they can measure.
Also - think about it. Advertisers with massive steempower upvoting themselves is would result in thousands of posts where most of them are ranking high for a while before downvoted. This would look like advertorials and the masses are starting to resent adverts, masked as content (ie advertorials).
Advertisers upvoting themselves (via massive investment) is only going to work for a small time until the masses mass downvote their articles. Adverts cannot be downvoted, only ignored, which under my proposed mechanics doesn't cost the advertiser.
Thank you for your response.
You are absolutely correct, and I agree, that advertisers currently prefer buying eyeballs through metrics. However, steemit could turn that model on it's head because now not only does buying SP give a ROI through advertising, but also gives ROI as a share in the overall revenue of the platform. Admittedly, I would be speculating on how advertisers may value that.
Also - You make a great point about the downvoting that I didn't initially consider. However, correct me if I'm wrong but.... a minnow's downvote does not have a large impact on a whale's post, right? But, I can see how the masses could make a bigger impact.
Hopefully, the masses come into the platform before an Advertiser scoops up larges amount of SPs and makes massive changes to the platform.
