How exactly would more users solve the problems?

Most of the recommendations contribute to a better experience for new users which than again could lead to more active users and less dropouts.

With more users more folks can more quickly learn the curve by helping each other.

If our current goal is more users, shouldn't we weight the incentives towards the newbs?
Seems a no brainer, to me.

Rather, we have spent the last 4 years doing mostly the opposite.
