If you think that the libertarian definition of liberty means the same thing as the Marxist definition of liberty, then you don’t understand either libertarianism or Marxism.
libertarian – freedom to succeed or fail without coercing or being coerced by others.
Marxist – freedom to absorb the resources and of others, because they have to supply by their ability if they want to or not. Marxism only works with either human nature is ignored, which makes it fantasy, or under compulsion, which means that there is no liberty.
Or as Danilo Cuellar puts it:
Voluntaryism is the most humble of positions since it asserts that we, as individuals, do not know what is best for other people. Most of the times we do not even know what is best for ourselves! How then can we, with moral self-righteousness, proceed to use the guns of “government” to attempt to force our neighbor to live the way we think he/she ought to live? This is hubris of the highest order! Voluntaryists embody true humility since they advocate for the complete self-ownership and property rights of every individual without exception! If it is immoral and criminal for me to commit a particular act as an individual, then it is immoral and criminal for any number of people to do the same act regardless of what they call themselves. Acting under the banner of “government” does not allow for exemptions of the universal laws of morality. There are no exemptions because we are all imperfect human beings! “Government” claims exemption from the laws of economics, morality, and mathematics. See politicians for what they are, liars, killers, and thieves who force you to pay them by threat of punishment. There is nothing noble or magnanimous about it; rather it is rife with chicanery and deception. – DC
