I am adding this comment as it struck me that you did not mention the best reason of all for using the exercise you mentally played with.

It is extremely likely that sometime within the next year or two, most currencies will drop in value - banks are getting close to bankruptcy again, despite the billions they took from us taxpayers not so long ago.

With Steem being at 13 to a dollar, the likelyhood of it dropping is not as likely and if it does, it will be to a smaller degree.

However, should the other currencies drop, steem will appear to grow stronger, since you will be able to sell Steem for more dollars (for instance).

The only major problem I have with Steem and crypto currencies, which nobody seems to talk about is: what happens if the internet collapses? or thanks to the UN it becomes so strictly regulated we can no longer use it?

lol - I just realised....if your scheme is based on curating, all those nasty little accounts who have no posts or comments, all they do is flaf, how would that affect the curating if they affect the earnings of whoever you curated? I have just yesterday seen people complaining about this exact problem, losing what they voted because of flags
