Final answer:
A state can survive without joining a non-state constitution, as seen in examples like confederations and stateless nations.
Step-by-step explanation:
A state can survive without joining a non-state constitution, but it may face certain challenges and disadvantages. One example is a confederation, where states retain their powers and form a loose partnership. The Commonwealth of Independent States, made up of former Soviet Union nations, is an example of a confederation. Conversely, stateless nations like the Kurds, Bretons, Catalans, and Basques face disadvantages as they lack recognition and involvement in international organizations.
