I somehow agree with your point of view, but the fact is that in the beginning everyone is searching for his or hers way on the platform and only through mistakes and experiences we can grow. And if there isn't any reward also for the perseverance and hard work done (even if some lack the artistic touch), the platform use will decline and so probably the interest. We all want to contribute and learn from each other so this should be done through each personal way and my belief is that the platform will react itself and reward those at some point... But, let's let for everyone to have a change and motivate them to persist in the beginning.
