I think that people can be absolutely free under libertarian policies in a capitalist economy. This ideal has never truly been met, because governments want control and religions want control and monopolies want control and pressure groups want control. But, in the future, evolution will allow civilization to reach near-perfection. For example, people of the dark ages would consider the U.S. today absolute perfection. The point is, in order for people to be free, people have to realize what "free" is. Free is not "freedom from financial obligations" as the electric bill is something you freely opted into. Free is not "freedom from living necessities" because the ability to purchase food, water, a house, and a car are something you only do if you are free (to that extent). Being free means that no one can force anyone else to do anything unless that person is forcing you to do something. Example: I cannot force someone to give me their money, but if that person previously forced me to give them their money, I can use government force to retrieve the same amount of money. This is called "justice". Justice is the only force of coercion in a free economy. But like I said before, throughout human evolution, we will refine our government, our society, our economy, and our ideals. Eventually, non-working systems such as feudalism go out of business and newer, more advanced systems such as capitalism start up. The only true problem, one that intellectuals are most afraid of, is that collectivism is just as sustainable as individualism.
No one can ever be absolutely free. There's always some sort of attachment that prevents you from reaching freedom. There are obligations to school, work, family. Not to mention that with each person you love and/or care about, you sacrifice a piece of your freedom in order to make them happy. The only way absolute freedom can exists is in a world where no one is working or going to school and none of these people have formed any sort of limiting emotional connections to anyone they know.
Absolute liberty is technically anarchy which is way more corrupt than communism.
You should have lots of freedom but be distracted from harming others or doing anything illegal. You can't do everything you want. There should be rules to keep people safe.
