@VeganMGTOW No, he is using the word "tax" with "poetic license".
He is not implying the tax burden or individuals relationship with government.
He is implying just as you pay a tax to keep the government at bay; loneliness is a "tax" required to gain clarity of thought, piece of mind, and mental growth.
@sardonicsmile Oh ok I get what You mean it Is weird kind of tax that actually can bring some benefits to the person that pay the toll
