In fairness, the examples we have of communist economies have all eventually collapsed, although it took many many decades for the USSR to do so. China, so far, hasn't collapsed. Does that mean there's something fundamentally different about it that avoids the fate of the USSR, Venezuela etc? Maybe. But it's not like "fails to be capitalist, will collapse" is totally specious reasoning. It's just extrapolation from past example.
