I believe that in order to keep chaos under control, it is necessary to live under a government. Without it, there would be neither a military nor a police force to protect the citizens. At best, people could band together to protect their friends/family, but that would do no good against possible external threats from other countries. On a similar topic, the U.S. would basically be eliminated from the global market since businesses would shut down shortly after the government was removed. People along waterways or with access to airplanes could feasibly continue to import and export goods, but the majority of the country wouldn't have that luxury. It would be up to these independent people to continue trading. Finally, without a government, medical care would be hard to come across. General medical facilities as well as research centers wouldn't have the funding to be able to continue their work. People with terminal illnesses couldn't be treated and would die as a result. Those with auditory, visual, or mobile impairments might not have access to tools they need to function (i.e. glasses, wheelchairs, crutches, hearing aids, etc). Due to less of the population being able to get vaccinated, the lowered herd immunity could cause multiple viral outbreaks as well.

I disagree that life without a government would be less stressful. For starters, you would have to worry more about your basic needs. Without people working, you couldn't just go to the grocery store whenever you needed more food. Instead, you would have to focus your time, energy, and resources into hunting, gathering, farming, etc. Not to mention, you would have to hope that you are or know someone who is handy that could help you build and repair your supplies/house.

And while I do agree that there would be more free will, I don't believe that the crime rate would drop. If there is nobody to enforce the law, what's stopping you from breaking it? (Consider what happens in 'The Purge' movies when everything becomes legal.) It would almost be necessary to steal on a daily basis in order to survive since, as I mentioned above, no one would be producing goods anymore.
