You’ve made a no true scotsman argument because all these other capitalist systems with their wage labour grievances and their accelerating inequalities tearing at the coherence of societies’ fabric are not _really_ what’s at the core of capitalism and if they just did it better then it’d be awesome.
The scale part comes in because what you describe - capitalism without wage labour - exists all over the world today, but only in the small. You cannot grow it to a country sized system.
