While we can't go back in time and not do things that were done, none of the things done are cast in stone. As we gain better grasp of the issues and dynamics of Steem, we can do things that best grow it's value, including changing or undoing things that were done in the past.
I do advocate changing some things, but the changes I advocate are not supported by the folks whose profiteering drain on growth those changes would reduce. Odd that. Anyway, there is tension between investors, who seek to grow the value of the investment vehicle, Steem, and produce capital gains, and profiteers, who seek to extract value from the investment vehicle, Steem, and hoard it in their own accounts.
Since Steem wasn't founded by seasoned investors, but cryptokiddies, the investment cadre isn't particularly robust. Either profiteers will learn by their mistakes, or they will keep making them, and Steem will not increase in value as a result of sound investment improvements if they remain dominant.
Time will tell.
