I want to, but can't believe in communism or anarchism, because there is no ONE practical evidence they can work, at least in the actual humanity (for tranhumans, maybe).

Even the "primitive" comunities have a basic form government... Even in classrooms students creates their own social structure and "game rules", accepted or not by the most of them.

Sorry. Anarchism and socialism (i mean REAL socialism, not the shit "socialist" governments of China, Korea and Russia) are just illusions that can inspire us, but are not real or sustentable. They are asintotes.
