In a free country like the US aspires to be, not every aspect of everyone's life must be mediated by the government.
Your argument undermines itself.
When the government fails to act, private parties may act in their own best interest. Private interests may be moral, not purely economical. Pushing Google to sell ads at a discount (compared to the cost of building a reputable website) is as bad as pushing a water dealer to cut their prices.
And finally, it's cold comfort to the thousands (millions?) of abused people for a rich elite to tell everyone else that they should merely lobby and wait until the government deigns to lift the yoke, instead of taking direct action to help.
so if you don't go into the different advanced axioms of set theory (way beyond the target audience of the article), the article is close enough.
