Licensing. The traditional locus of regulation of health services and insurance in particular, licensure of health professionals, insurance brokers, and others has been state governments. The Internet is completely oblivious to political boundaries. The fact that consumers in one state can purchase goods or services from other states over the Internet without paying local sales taxes has already raised serious long term fiscal policy and equity issues. These issues will eventually force a rethinking of state and local tax structure.
A similar rethinking of licensure policy may ensue. Supervision of licensure is the most powerful tool governments have in ensuring that substandard practitioners do not practice medicine. How this method of supervision remains viable in the emerging networked age is a serious policy question.
