It's not even close to the best we can do. It is, however, the best we can do, given external control of the Libertarian Party by the FBI/CIA/unknown. I'm very confident that the LP is controlled by one man who is under external control. The dilettante "libertarian billionaires" then assume that the LP is "doing the best it can" when the opposite is true.

In order for them to really pursue freedom, they'd need to get involved with the LP, discover how it is being purposefully manipulated toward failure, and correct the problems.

Only John McAfee had the intellectual integrity to attempt to do this.

It's more comfortable to just be a libertarian billionaire in the current system. Also, correcting the LP involves a large degree of risk: What if the central bank kills everyone who bootstraps serious opposition against it? Most people like Charles Koch, Elon Musk, and Peter Thiel are smart enough to see that the current system is sociopathic.

For all of the prior reasons, the USA lacks a serious libertarian effort equivalent to even the level of the Founding Fathers' and abolitionists' effort.
