Libertarians are big on individual rights. Anything that helps the group at the expense of the individual is considered theft. A good example would be taxation. Taxes are theft because I work for my money and the government steals it so that someone else can benefit. In a way, this is a form of slavery. Therefore, libertarians aren’t a fan of taxes.
Two main tenets of Libertarianism is that one of the purposes of taxes (or maybe the only purposes) is to protect private property and to prevent harm. This got me thinking: how do taxes protect my private property? It can’t be a police force because the police protect all forms of property, not just mine. So according to Libertarianism, that’s theft because my money is protecting someone else’s property and preventing someone else from getting harmed. It can’t be the military because that’s not protecting my private property, although it is protecting me from being harmed, but this also includes everyone else. Thus, my money is protecting everyone else.
So how can the government protect my private property without interfering with anyone else’s? I don’t think it can. Not unless it taxes everyone for the benefit of everyone. But if this happens, doesn’t this undermine the whole philosophy of individualism?
