If we want to empower clients/site-builders/marketers or whoever ... to build (ambitious) websites with low code, then there is no other way. The lack of good themes has always been a big obstacle for Drupal.
The costs for small and medium projects would decrease with such a theme marketplace. Time-to-market would be extremely shortened.
But the devil is in the details ... the current discussion is taking place in the #drupal-cms-marketplace channel on Drupal Slack.
