Is there any alternative to Capitalism, Socialism, Libertarianism or Communism or something completely unrelated to any of those?

If you look into the political spectrum, the answer will become apparent. From left to right, left tends to restrict business freedoms but allow personal ones. Right tends to restrict personal freedoms, but allow business freedoms. From up to down (or north to south if you prefer), more authoritarian increases the number and severity of restrictions and libertarian reduces them. You can find pretty much all political viewpoints somewhere within that spectrum.

Well, there is always Anarchy, where everyone turns against one another and thins out the population leaving only the most heartless, murderous and dangerous in charge of the population that is now only 1/10th of what it was.

Anarcho-syndicalism looks interesting.

Yes anarchy.

I see no failure in capitalism.

there is no answer but it is good for us to look for one
