Exactly. What the author is emphasizing is that when you remove God from the equation (and by God, I mean the Judeo-Christian God), then whether your philosophy is Capitalist based or Communist based, an emphasis on a godless philosophy will ultimately lead a Nation to a social dystopia. In other words without reference and deference to the God who gave us our Natural Liberty, the end result will be that we will lose whatever Liberty God has granted us.
Certainly a Nation can tolerate Atheists, but when a Nation turns its back on God, when the Nation itself becomes a reflection of godlessness, then ultimately whatever gifts God has bestowed upon that Nation will dry up.
Ayn Rand’s and Saul Alynsky’s godless philosophies ultimately both lead to the same destination.
When a person or a society subscribes wholly and completely to either a purely free market or a rigid command economy, the preoccupation is with how to live, never addressing the purpose of that life.
