Yeah. I once had someone point to Norway after I stated that socialism doesn't work in practice. "Oh, okay," I said. "So all you need to make socialism work is a ton of oil and a bunch of capitalist countries to sell it to. Gotcha."
Norway is a capitalist market economy.
However, there is heavy taxation and some government ownership of industry.
Anyways, your friend is wrong to use Norway as a case to argue for socialism.
And someone else to cover you militarily so you never have to budget for your own defense.
