This is some sort of No True Scotman. If you are truly going to follow this road, then there hasn't been a truly Socialist or Communist nation either, not truly.

In this case, we haven't made any inroads in deciding about the relative merits of Capitalism, Socialism or any other -isms, since there haven't been any nations that implemented them. Not truly.

I don't know about you, but it seems like a fruitless viewpoint. I believe Capitalism as practiced in the real world has run its course. This, of course, doesn't mean it's going to go in the next few decades, but I believe its days are counted. Call it optimism.
