Because anarchy can't exist for long. If nature abhors a vacuum, it abhors a power vacuum most of all. That vacuum will quickly be filled by the strongest person with the most guns, and the results will be anything but libertarian.

Where in nature is anything resembling the governments than man come up with?

Everywhere, sorta.

Animals vote.

How is that different than the anarchy where people vote with their feet and flee from situations they are not agreeable with, or act in a manner and stronger individuals choose to honor it?  What you have in man-made systems is a situation where the society collectively gives certain individuals the ability to inflict pain and suffering upon non-compliant individuals to get them to comply.  Where is that in nature?
