For the success of Steem blockchain we should be focusing on the value of market cap instead of the price of steem.

This is where you lost me. The price of steem is directly link to the rewards on the platform, the lower the price the lower the rewards which means less investment/overall interest in the platform.

. But if we take a look of the bigger picture of the system, it's actually really interesting experiment and it should be closely observed and researched.

Why is it an interesting experiment? what is the purpose of the high inflation? what are they trying to achieve with this inflation?
