The first is, anecdotes are interesting, but is there data that supports this? It seems like there are too many variables, and that at home care may not help in all circumstances anyway.

Secondly, "getting proper care from someone who actually cares about you" by which I guess you mean a family member or close friend. Is not viable is many circumstances...

Finally, I guess it comes down to "what do you actually do". If it proves helpful, what can you do to promote this? Fund family member to quit their jobs to care for relations? It seems like that would be open to abuse and difficult to administer.
