I think your definitions are confusing.
Capitalism being "an economic system in which wealth, and the means of producing wealth, are privately owned, and that land, labor and capital are owned, operated and traded, without force or fraud, by private individuals either singly or jointly", then saying something like free enterprise (without capitalism) is sort of a contradiction.
You should also make a better distinction between capitalism, mixed economies and anarcho-capitalism, for semantics sake
