You're just running away from a complex thing you don't understand but has a lot of traction, to a simple thing which you understand but has no traction. My strategy is stick with the former and educate myself more. Different strategies.
I generally think a lot of anarcho-capitalist theory to be obvious nonsense, but on that, they have a point.

The reason why you've never heard of it it's because it's not a huge boon to society. In the vast majority of cases it's an entirely pointless thing that you do just because you can.

"This approach eased financial conditions in the past and, so far, looks to be effective again. Stock prices rose and long-term interest rates fell when investors began to anticipate this additional action. Easier financial conditions will promote economic growth. For example, lower mortgage rates will make housing more affordable and allow more homeowners to refinance. Lower corporate bond rates will encourage investment. And higher stock prices will boost consumer wealth and help increase confidence, which can also spur spending. Increased spending will lead to higher incomes and profits that, in a virtuous circle, will further support economic expansion".
