A person is born helpless and travels a long road until adulthood. During this time, they are completely dependent on other people who are stronger, smarter, more responsible, and easily make decisions for them, for their own good.
In adult life, a person has children. Now they, as a strong, smart, and responsible individual, make decisions for them, for their own good.
The idea that in a complex society there must also always be someone strong, smart, responsible, and making decisions for everyone for the common good seems completely natural, because it grows out of direct life experience, gained, moreover, during the period of growing up, when all new information is best absorbed.
If a person considers themselves strong, smart, responsible, and so on, then the thought of guiding others in the interests of their own good is completely natural for them.
Thus, life experience dictates to us not libertarian principles, but a clear and familiar paternalism—a worldview based on the principle of transferring responsibility for oneself to those who are stronger and more experienced. And what are libertarian principles associated with in this context? With teenage rebellion. That is, with a phenomenon that is inevitable but transient, which every person must outgrow in the process of maturing; otherwise, they will simply get stuck in this infantile state and will not be able to succeed in life.
