So in summary what is your point? That Steemit is a scam because the developer did not alow the miner "establishment" to get a hand in the project? Or that it´s a Ponzi of some sort (even if you are not required to buy in but can still benefit from the platform)?
I guess you can argue it has flawed design. So you are in favor of a project like the Yours network?
In my opinion the Yours network is more of a Ponzi. Or rather a platform where users can create their own Ponzi scheems.
On that network you can earn money if you are a content creator (When and if the project actually comes to life) if someone is willing to curate your content by transferring money to your wallet.
The curator can make money only if someone else curates after you. Thus the last curator will be holding the bag.
I am not saying Steemit is perfect (it certainly isn´t) but I do not see any positive proposal in your post.
