Upvoted and thanks for introducing this item for discussion. There are pros and cons to more regulation versus maintaining the freedom (little 'f') that we have now. It's unfortunate some choose short term greed over long term health of the platform, but I also understand that SP holders want to make a return on their investment. 

Hopefully, moderated communities will curb these tendencies somewhat, and maybe a higher price will encourage people to use their Steem for more active investments to develop this ecosystem, though these problems always will exist on here at some level if we let them. I agree with @lukestokes that achieving consensus on this will be difficult, but it's definitely worth discussing.
