Coach Smith here again.

There will always be a need for specialists. And community support for the
activity, widespread knowledge of the basic principles, and sufficient
"safety nets" to minimize injury. For lots of activities, not just
breastfeeding.

Take swimming as an example. Nearly every person can learn to swim. Some are
frightened or traumatized because they had a bad experience initially, then
won't try again - and will often try to discourage others from trying. Some
will intuitively learn just by watching others swim (easier where there's
water around). Some will do great with just a little basic instruction -
that's why the American Red Cross and other agencies have training programs
for instructors and sponsor many levels of lessons at pools and beaches.
Some swimmers will get into trouble - that's why public pools hire
lifeguards who are trained in rescues. Some swimmers will decide to go
beyond the basics and become more skilled - they often join teams coached by
dedicated volunteers and experienced swimmers. If they want to excel even
further, they hire professional coaches and trainers who have college
degrees in physical movement with additional specialized training, and
travel to large swimming events. Some swimmers at all levels will become
injured and need to work with a specialist to heal their injuries while
continuing to participate at some level.  Some will have medical or health
conditions and need skilled help to be able to continue swimming - such as
people with arthritis, asthma, or orthopedic limitations. Some will need to
use equipment to learn a new skill, strengthen or correct techniques, or
provide support during rehabilitation from injury. And so on.

Not everyone needs an Olympic-caliber coach to learn how to swim.  However,
those designing education and training programs DO learn from the
Olympic-level expert swimmers and coaches. The more you know about the
activity, the fewer mistakes are made. At all levels.
