I belonged to a free-market economic discussion group years back. We had heated discussions with people over this exact issue.
We had complex thought experiments that went through the entire process under the conditions of a truly free market-system and true Liberty. We used only ice as the product delivered.
What was concluded was that a system without any government interference whatsoever (i.e. let prices be what the may) that what your call greedy was in fact the superior method to deliver needed goods in the most timely fashion and at the least cost.
Space does not permit me to explain in detail, but the fallacy of blaming "greed" is strictly the result of the indoctrination of progressive ideas.

Monopolies are bad, whatever their form.
