No, in fact a 100% free world does not exist. And a utopia will never happen. Why can't this happen? For you and for someone else a perfect world can be different. For you it may be everyone gets to live in shelter and gets at least three meals a day, and fresh water. To me that doesn't sound bad, but some crazed people out there may disagree. Possibly they want all African Americans to have no freedom whatsoever, or even locked up in cages!

You're most likely asking yourself, "How is locking people in cages FREEDOM?" Well, of course the African Americans wouldn't be free but the person that wished for that to be true is, not that its really helping them and their rights, but for satisfaction, so they get what they want.

For example, many (not all) white cops shoot black people, because they felt they were going to take out a gun from their pocket, but really they were just reaching for some spearmint gum. At least that's their excuse. I may be getting a bit off topic here but I strongly believe that you shouldn't pull the trigger unless you factually are in danger. Even if the person did have a gun, were you really under attack?

Now, possibly a better example: Libertarians believe in no or very little government, and I personally think that wouldn't work but anyways, if you are a communist a libertarian world would for sure not work for you.

Even if 99% felt as if they are free, that 1% doesn't. And that my readers, would still not be a free world for everyone. Of course they're should be basic rights for everyone, such as gay people being able to marry, but homophobes will disagree with that.
