"I can understand the hatred many people here have toward Standard Oil or other big gigantic life-controlling entities.
The step to remove Standard Oil dominance is to find, create and nurture alternatives. For example, I started buying petroleum from a small independent refiner. I'm using some of Royal Dutch Oil Company products like their lubricants and ointments. I'm using whale oil for indoor lighting.
So I'm diversifying a bit though they can engage in price fixing. This reduces the monopoly power of one single entity.
Blocking Standard Oil, Royal Dutch or another big provider will not work and if it did, it can have severe consequences. Most people (and politicians) are ignoring the massive productivity benefits that Standard Oil is bringing. It can be used for evil, but the productivity it brings is paramount.
You can't fight Standard Oil by blocking it or destroying it. There is a reason that Standard Oil is huge: It is magical and there is no usable alternative.
To remove Standard Oil monopoly you did what Standard Oil did for the Cleveland or Pittsburg cartels: You build an alternative. It is possible to have multiple alternatives for oil like for steel or railroads (though we have only two).
The reason we don't? Standard Oil won. Carnegie Steel won. North Pacific won. Everybody gave up and just accepted it. Now everyone is screaming of "regulating" these guys. Trust me. This how you get closer to your demise (politicians and current day governments) than to their demise."
