fundamental question for steemit 1, SNS based on the Rewards ?

Is the SNS based on the Rewards possible ?

All of our problem were occurred due to the distribution of the rewards.
This problem seems a strong obstacle for the Steemit for developing as the SNS, in my opinion.

Facebook did not give any rewards for the accounts, but lots of people like to take part in the Facebook.

We must admit that the growth of the accounts was stopped due to the rewards.
The rewards was an obstacle for the ordinary people who had not so much SP.
