First of all those Tokens sold in a public auction would become regular Steem Tokens with all Voting rights etc... and this would also solve the problem with Ninja Stake in Steem, because now this Stake can be bought by many investors.
There is also the SMT and Community project that brings more features to the Steem Economy. And overall the community has shown a lot of strength and Steem is in the Media, if Justin would act wise he would use the attention to turn the situation around.
