The point of the distinction is to clarify the problem, not to say it's easy to decouple top-down crony capitalism from a more bottom-up free market capitalism.
You can also ask the same question from the other direction:
How do you expect expanding/centralizing political power not to progress into crony capitalism?
There are ideas about what to do but it's a tough political problem.
There is too much disagreement, ambiguity, and complacency about legislation to hold crooked politicians and rent seeking firms accountable to the satisfaction of those that see a problem with it.
So the first step is to spread awareness of the distinction so there is enough political pressure to counter it.
