This is an extend of my answer on Should we initiate assisted dying?
As how I see, lack of experienced users is inevitable and we should have accepted that as a part of a growing site. The essence reason for the dying is lack of downvotes. Voting is the most important thing in the SE model. But if downvotes are that important, why is there a rep requirement for downvote privilege?
The reason for requiring 125 rep to have that privilege is to expect you to involve and have more knowledge on the community before voting. But if knowledge on medical is much more important than the knowledge of the community, then why don't we encourage new users, even lurkers to downvote bad posts? We may have a risk of having non-well-intended downvotes, but will the risk overcome the benefit? I think if this site is dying anyway, then it doesn't hurt to have a try. At best it will survive, at worst we have a study case.
Tl;dr: not enough downvotes on bad answers vs good answers get downvoted by trolls
