When the government is working as intended, and have not abdicated their duties to the people, the government at least has controls over what they can and cannot do. Yes, they have a monopoly on violence, but they also in theory have lots of controls.
For example, the government cannot silence your speech, but a private company can. The government cannot share your data with others, a private company can.
Unfortunately the government has abdicated their duties and so you think they are worse than a private company.
