What I would like to see during the growth phases of Steem are buy-backs in Steem from the owners using money earned via monetizing our platform

The thing is, as far as I know, Steem "owners" have no plans to monetize the platform. So there will be no funds for the buy-back.

(Anyway, what you suggest would only be possible in case of a standard, centralized company. Here in Steem there is no such thing as "owners" who could profit from monetization - everybody is an owner to some extent).

If you'd like to know what the alternative to monetization is, please refer to this post:
