Lets take your scenario one step further. The entrepreneur now uses his newly gotten weatlh, buys up some neccessary infrastructure that everyone relies on (for sake of argument lets the food supply) and raises the price to 26ct, everyone in the society but him starves to death and no violence was used. At what point, if any, should a hypothetical state step in?
Nowhere? If you sell your only milk-giving cow, don't be surprised if the prices of milk increases. You're using "buys up" like the people selling had no choice. They have plenty of choices: they can refuse to sell, they can refuse to cooperate with the new owner, they can go and build new infrastructure. Ultimately, a property owner is not a monarch, and can't force anyone to do anything. These techniques have been used in to remarkable effect in the past to peacefully compel good behavior. See Charles Cunningham Boycott or Mahatma Gandhi.
