I believe "Just business." is
the libertarian position.
The libertarian position is defense and respect for individual rights. This includes the right to freely engage in business, but there are a lot of people that got into libertarianism for other reasons, for example civil libertarian issues.
Not all libertarians are great businessman not they have to be. We just know that allowing a free market to happen will benefit us by having better quality products and lower prices as opposed to socialdemocracy that always helps the oligarchies.
EDIT: Btw op great chart. Shows that Bitcoin is more stable than most people think.
