Does the world need governments?

I cannot help but notice how insane our world really is. The coming elections in America underscore the fact. Most of what the political parties actually campaign for is extermely irrelevant to the function of governing a nation. What exactly do you think governing a nation would or should include? To me there are only a few key things that you want to outsource to some organized entity so that you do not have to step up and do it yourself as you laze on that beach in Hawaii. 1. Make sure no one bombs the beach while you are napping. Ergo - need a military presence to keep bad guys out. Get the Government to manage this function. 2. Make sure that the road signs are consistent whether in Hawaii or New York city so my beer addled brain can process information about exit ramps quickly and without confusion. Ergo - need a standards body to make sure we know what we are buying, driving and selling. Get the Gov to manage this function. 3. Make sure there are trees on the beach to nap under. Ergo - make sure someone does not go at all the green on this planet so they can build more condos. Get the Gov. to protect some land with nature intact. 4. Make sure I can add and subtract the money at the beer store. Need decent education (also to decide whether to buy Japanese beer or Belgian) to process basic information. Get the Gov. to ensure that at least elementary education is made available to anyone that wants to get it. Rest is all humbug and the people should stop wasting time voting for someone who harps too much about these idiotic things. Ergo - no one left to vote for!
