There are problems beyond just supply and demand. The reason in my experience that someone might use the term transactional is that at any given appointment, most doctors will only choose to focus on one or two topics or concerns. And generally, to get any sort of treatment option for those they'll need some sort of code for insurance to reimburse for the visit. This is especially true for specialists, whom if you visit enough doctors you'll realize push procedures or specialized tests very heavily because that's what makes money. In the current system every single aspect of medical care must have a price tag attached, must be composed of transactions and codes, or the doctors won't get paid. When the concept of "what is the diagnosis" implicitly morphs into "what is the billing code", medical care becomes a fractured and transactional experience rather than a holistic assessment. (And for any doctors reading this, I know that "holistic" is one of those quack trigger words, but those quacks are responding to an unmet need even if their treatments and diagnoses are pure bunkum.)
