bad examples are EU, USA, China, Russia
all want to flood the market of the other one with easy to mass produce goods, like meat, wheat, electronics,
No one is trusting to flood anyone. Companies are selling as much as they can and getting their profits. If some hot country shouldn't struggle for its agricultural sector instead of buying what they need abroad?
in order to keep the currencies value pairing high, but cant do that because they block each other off it,
No. No one needs to have an expensive currency. It is much easier to buy anything from russia while living in EU because for expensive EUR you would buy cheap russian rouble and cheap russian goods.
The aim of the central banks is to keep their currency stable and sometimes slightly deflate it (for example up to 1% per year) in order to provide some advantage for its exporters.
during the existance of the soviet time there where many directors with their own currencies in the soviet union who needed ressources for space exploration projects,
Comrade Satoshi is a grandson of a comrade Stalin. True.
but stuff like that doesnt exist now. because everyone is just trusting into the central bank of those democracies.
You have to rely on your central bank simply because it is regulating the monetary policy of the entire country and not only printing money that are in your pocket. So even if everyone would issue his own cryptocurrency and those coins would grow to the high price everything would collapse simply because the real economy would degradate and people would return to the stone age.
