But in the general Anarchism, Ancaps are called a bunch of hijackers who came in late and adopted the term "Anarchy" while defiling the original meaning. The term was originally used to mean various forms of Anarcho-communism.

I always have to suppress a laugh when I see Anarchists saying communism is the worst, since Anarchy is just a fall-out of communism with less morals. (Same is even more true for the voluntaryists.)

Now tell me 10 groundbreaking innovations coming from Scandinavia after their soft-communism/welfare capitalism/leeching on free markets.

Well, the leeching off free markets seems to work great. Minimum wage is higher than in the US (most capitalistic 1st world country), as is the number of millionaires per capita and the % of people who advance from lowest income quarter to highest income quarter.

As far as innovation goes:
Sweden alone invented the pacemaker, the adjustable wrench, the Tetra Pack and the three point seat belt and the zipper.
Too old?
How about skype? Or a new HIV detection method?

Also, in related news, "communistic" China has just overtaken the USA in the numbers of scientific articles.
