No, the price of anarchy is that if you want to make this your cause, you do so yourself, at your own expense, and you recruit help through persuasion, not force.

Take Nazism in the 20th century, for example.  You want to fight it, more power to you, but drafting and taxing other people to do so was wrong.  Others might have seen it as evil but not as evil as, say, Stalinism.  Or may have felt there were better ways to combat it, or whatever.

Likewise with Islamic extremism in the early 21st century.

And many, many other causes.

Just because something is evil does not mean you have the right to use force to make other people fight it.
