I disagree with you as this decision not only harms newcomers but could be the beginning of the end of steemit! the authors at the end will earn less no matter if the content is of quality.
new users can not be expert authors as the final consequence will withdraw from the platform and fewer users will affect the value of the steem because the value of it depends on the transactions and the trust your users have in that currency.
who decides which post is quality a user can create a content in which it takes 20 hours and consider that its content is quality but that does not mean that other users believe the same!
