As the world becomes more accessible to everyone and increasingly interdependent, national monetary systems and currencies are creating unnecessary blocks to growth. The disparities of currency from one country to another help perpetuate world conditions of economic instability, and too many people expend their energies without gaining the necessities of life.
For over a century nations have been the political units that have carried the thrust of economic growth. Each nation has a unique monetary system. This has been critical for the subsistence of the world's people. When a new nation is formed, it has always established its own currency and means of exchange. This makes the new nation an entity and means that the government has some control over the economy.
