"If this was a perfect world I would be a Libertarian too "
If this were a perfect world, I would be a Statist because I would then know that government is populated by veritable angels and not corrupt individuals, the most corrupt among us.
Your thinking is totally backwards. The very reason to be free is precisely that man is fallible. It is through freedom to interact and to KNOW that we can minimize the hazards and risks cused by thieves, cheats and liars. Instead, with a government, people tend to lower their guard, thinking that Daddy Government is there to protect them - leading to what we've seen for years.
