3D means 3 times more stable nations

EU Commission President Juncker is hailing the euro as a symbol of unity, sovereignty and stability. However, the EU is setup just like an extension of ordinary 1D nation states: D1, D2 and D3 matters are legislated by the same politicians. Imagine the 3 dimensions of a society were disentangled and then re-linked to the corresponding, same dimensions of each member state. As a result, the stability would be triple strong.
