The best form of government.

Socialism... because socialism.
Monarchy is impossible without strict control over the upbringing and training of heirs to the throne (which can only be achieved with the latest technologies in genetic engineering and psychology) and inevitably leads to periods of stagnation and conservation, which provoke reformism and arbitrary absolutism that sacrifice the citizens of the state.
Theocracy is a wonderful regime, but it is impossible in a world of triumphant atheism. Not a single country on earth is inhabited by sincerely believing people... therefore, theocracy is doomed to become a dictatorship of lies and hypocrisy. More often than not, the clergy are the most convinced godless people, and this undermines the entire moral structure of such a society. This isn't the 7th-11th century; that won't work. Moreover, the primary role and significance of theocracy is to prevent wars and conflicts within its own religious space.
Communism has never once been embodied on planet Earth, so in my view, it should be excluded from the poll options. There is nothing to compare it to. Aside from that, naturally, triumphant communism across the entire Earth would be a true paradise. It's just that it will never happen. Marxists are prone to dubious social experiments, improvisation, and cannibalism. I would only support communist-necromancers, collectively resurrecting Marx, Engels, and that whole crowd of 19th-century theoretical economists, for the purpose of faithfully heeding their instructions :D
Anarchy is absolute evil. Man is not, by nature, a perfect creation, the pinnacle of creation, as the humanists and figures of the Enlightenment era claimed, but a filthy animal drowning in self-deception, stupidity, and egoism. There will be no society without a state, because people will devour one another without the punishing sword of justice hanging over their heads. People are not sheep, who need a shepherd only for protection from wolves and wandering off, but rather a pack of wounded sharks. Here, the "shepherd" can be either the Fish-Bringer or the Harpoon-Thrower. The first attempts to keep the sharks from eating each other by sacrificing more "natural" food to them (though he knows that once the fish is eaten, the wounded sharks will still attack each other, because blood is blood), and the second simply kills a few of the quickest ones, sending the rest fleeing—which has a slightly better chance of preventing the devouring, albeit at the cost of casualties...
Democracy is a utopia, unless we are talking about a Greek polis. It is possible only when citizens directly participate in the activities of the state, when every adult person is a "deputy" or "senator." And of course, every citizen must be personally acquainted with the supreme leaders of the state. Everything else is not democracy, but various versions of ochlocracy and oligarchy. The modern glorification of the idol of "democracy," the thousands of legal bows paid to it, and the offering of bloody sacrifices repel me even further from this political idea. A state where there are poor and rich, lazy people and workaholics, freeloaders and dependents is a wrong state.
Socialism is closest to the ideal in terms of eliminating property differentiation... since it does not throw itself into extremes like communism. Social protection for at-risk classes—pensioners, public sector workers, the disabled—is quite sufficient for minimal justice. Stripping people of the right to private property and family and abandoning money are far too drastic steps that cannot lead to anything good. The external market, in my view, should be entirely controlled by the state, and big business should be subject to monstrous, predatory taxes (frankly speaking, this is a norm of justice). At the same time, the state should not excessively interfere in the lives of people. Demanding lives for a war started for material or ideological gain, interfering in the personal lives of citizens with bloated legal acts concerning everything in existence, seizing what has been earned through honest labor, and stuffing brains with propaganda. The state was created to protect people from one another. And it is sad to see a situation where people need protection from the encroachments of the state :smile27:
