ABSTRACT
Solidarity can only be sustained in closed communities; without restrictions on entry or exit of a solidarity community, no one could be coerced to contribute to cover the costs of the benefits and services distributed, or be restrained from consuming these benefits and services. Free movement would thus make impossible the financial sustainability and the efficient planning and provision of welfare (Offe, 1998). Entry into and exit from solidarity communities of healthcare have been territorially confined in the European states. The principle of territoriality basically defines who has the right to access health services and coverage for the ensuing costs, and who must contribute for the maintenance of the healthcare system and the planning of healthcare facilities.
