Wow, Zinnia, your first describes me pretty well! After all, anarchy is the absolute best system for humanity, as long as each and every human is concerned with actually building the most value to be able to trade on. Unfortunately, most of us are not. Most humans don't want to build value and wealth, rather just get credit for what value and wealth is there, whether they had anything to do with it or not. This is why we actually need some form of government, some way for people to get together, discuss, and decide the best use of resources. If we all, each and every one of us, just do whatever our little hearts desire, we're alone and weak, and even those of us who want to build something are left unable to do so because our lack to access to resources, and lack of access to necessary skills.
Without government, we'd have no roads. No major construction of any kind. In this situation, we'd be much slower moving goods around, and they'd become much more costly.
Without government, our farmers are dependent only on themselves to be able to fight off those who'd simply steal their crops, leaving them less time an energy to actually grow them. Meaning less food for everyone.
Without government, we'd have no standard of defense against rogues who choose to take, only our own individual will and capability to kill those who take from us.
Basically, as good as anarchy sounds with the best of people, the people we have available means we'd devolve quickly into tribeless hunter/gatherers, only the strongest and most ruthless able to survive. Because we'll be too busy fighting the Hoppeans who think they're in heaven, up until the time that kindest and most law abiding people who manage to survive the chaos say "screw this", band together, and stab every Hoppean in the back . . . forming the first new governments in defense against the smarter Hoppeans figuring out just exactly what golden opportunity they had in front of them and pissed it away because they were finally allowed to take what they pleased and thought there'd be no consequences.'
More basically . . . humans cannot exist without government because humans won't allow it. Our only real choice is to make it the best government possible. If the best government is a limited one that leaves individuals doing mostly as they please, there's plenty of undeveloped countries where you can do that. If the best government is one that bands together and attempts to build greater wealth . . . remember that most of the highly developed nations in the world are classified as socialist. And the rest are "in danger of becoming socialist." Ironic, isn't it?
