But it has no boundaries: knives can be dangerous for "stupid population", medications can be dangerous, wearing incorrect clothing... and as a result we'll get an anti utopian world. Government consists of the same people who can make mistakes which can be dangerous and even much more dangerous than a mistake of someone outside, but we don't ban governments because they have a positive meaning also.
Don't absolutize governments, their decisions and fears can be as wrong as of someone else of "stupid population".
The problem with the government is that they are trying to control all aspects of the life of the population of the country. They want to monitor our every purchase, every payment, that everything is available to them, that every dollar is taxed. But no one likes to live under surveillance, if a law-abiding person works and pays taxes, then he does not need such control. Governments are not perfect, you are right, they are made up of people who can make mistakes.
