I've really enjoyed this thread and it's many far-reaching implications.
 Everyone has shared excellent points.  Our opinions on this matter will
affect how we counsel breastfeeding mothers.  The doctor who doesn't support
breastfeeding or the value of breast milk will give different advice than the
doctor who supports the value of both, or the doctor who supports only the
nutritive value of breastmilk.  The breastfeeding counselor, whether lay or
professional, in-hospital or out, will counsel a mother differently based on
her deepest beliefs about breastmilk and breastfeeding.  We all have a
philosophy of breastfeeding!

As a volunteer lay breastfeeding counselor, I need to justify (to myself!)
why I give so many hours to helping moms breastfeed.  The short answer is to
help make this world a better place to be.  Unfortunately, I don't think
expressed breast milk will do the trick here.  The hand that rocks the cradle
rules the world--unfortunately, the cradle is increasingly being rocked by
institutions, manufacturers, and care givers without strong attachments to
the child.  Every time I help a mom give her baby breastmilk without
physically breastfeeding, my deeper motivation is to hope that she will
physically breastfeed as much as possible, form a strong bond with her child,
and be a better mother for it, benefitting all of us.

I have a lot of trouble with the "breastfeeding--it's not a lifestyle choice,
it's a health choice" theme.  EVERY health choice is a lifestyle choice.
 Giving breast milk from a bottle and breastfeeding are both lifestyle
choices (yes, often intertwined).  Many of the health benefits of
breastfeeding are lost when there is no physical contact between the mother
and the baby, assuming we define health as more than nutrition available
through an expressed product.  And breastfeeding IS much more than that!
 Ultimately, our society will suffer/is suffering because of this.  IMHO  :-)
