I would argue, that free markets are very good in fullfilling many needs. Since requests can be expressed with a price someone is willing to pay. But there are market failures in particular cases. How much does someone have to pay for an action that reduces the freedoms of everyone? To whom should they pay it? And how do they pay it? Examples are: Littering, emitting carbon dioxide, emitting dirt water, poisoning water sinks, poisoning the sea. In places, where nobody is the rightful owner of a place or street, who takes other accountable for insustainable behavior? I think we can find good regulations for such externalities. But they are not naturally selfregulating. Since most people do not actively request good airquality with money. Every individual is dependent on collective decisions to keep polution to a level, that is not harming our health. And for such solutions burocrats are needed in my perspective. And I would also respect that every human grows as a dependent creature. So we should accept, that there is no opportunity for human life, without people that gift to others without getting an instant return. Nor a contractual counter deal. Therefore the idea of "egoist behavior is good for economy" is simply a lie. I can see, that free trade offers win-win situations. But egoistic tendencies do not add additional value to that.
