The Hippocratic oath is similarly local in scope. Individual doctors try hard not to cause harm to individual patients, but the medical establishment causes massive amounts of harm, by:

- developing treatments for chronic symptoms instead of curing diseases

- being unprepared for pandemics

- making health care unaffordable except through employer plans

- promoting wrong nutrition guidelines for decades after the evidence was in

and more.

To have good outcomes you need ethics at both individual and system-wide levels.
