At present I suspect we need these guilds to grow. If they are not regulated in the future they may be the downfall of Steemit.
Why do we need guilds to grow when the active user base really isn't growing? I would argue that we need less guild manipulation of rewards allocation. I don't see how they can justify 200+ votes every day when there are only 600-800 total posts.
And why would we need regulation of guilds? Why not just stop creating these guilds? They wouldn't be an issue if whale accounts were not behind them. That's the main problem. The guilds are being created in order to use whale power to subjectively distribute rewards "more evenly." This distorts the actual market for content. Adding another layer of "regulation" to a very tiny and distorted market doesn't make much sense.
I understand your argument, but I think the simplest resolution is for the whales to stop delegating their stake in this manner and to stop approving of it to be used for the Guild's self-voting of their own posts. The whales in question here have the ultimate power of decision-making.
Well we either go full free market or work on the guild system to make it more efficient. The problem is that there are people who will constantly plot to vote share which gives an unfair advantage.
Whales want the curation income but don't want to read hundreds of articles each day. Perhaps if a non voting income were offered in place of proxy curation the whales could be persuaded not to guild vote and the system would begin to even out.
