Final answer:
Dr. Lopez's policy of not accepting insurance reflects libertarian viewpoints and has implications for access to medical facilities, potentially leading to moral hazard and adverse selection in healthcare.
Step-by-step explanation:
If Dr. Lopez did not accept third-party insurance and required all patients to pay at the time of service, this would align with certain libertarian views mentioned in the politics chapter, where health care costs should be borne by individuals and reflect the actual cost of care.
Dr. Lopez's policy would also introduce issues related to access to medical facilities for poor populations, as those without insurance might defer care until they are very ill, often relying on the more expensive emergency room care as their health care option.
Moreover, since insurance helps in spreading the costs of health care and reducing immediate out-of-pocket expenditure for patients, Dr. Lopez's approach might limit health care utilization to those who can afford it, potentially leading to moral hazard as well as the issues of adverse selection.
