There is a popular basic science demonstration where you pump gas into a flask. In low volumes, the gas fills the entire flask in a uniform distribution. Same situation in high volumes. As you increase the volume of gas the individual gas particles begin to move less and less.
This makes an obvious though valuable analogy to human societies. The more bodies added in a limited space, the less freedom afforded to each body. As populations increase, regulations and intrusions upon the individual increase. Simple matter of bumping into your neighbor.
