> One person can't lay claim to all private property through voluntary exchange. What was he exchanging for "all" the property? Yet, that is what is how things are currently trending if you change one person to one group. When you own the means to produce what others need for their survival you can exchange those consumables for more production capacity -- the one side gets things that are valuable for a short time and fade to zero value and the other side gets things that increase in value or produce more value over time. It is a virtuous/vicious spiral (depending on what side of the equation you are on). So, not all property is created equal either.
