perhaps it would be more accurate for me to say that capitalism in the pure platonic sense doesn’t really exist,

I agree with this without any reservations.

and tends always towards crony or state capitalism where the power of the state is used to funnel money and power towards the holders of capital rather than to provide a free and fair playing field for economic actors.

I take exception with "always". In the USA for example, there have been many notable exceptions where state capitalism implemented protections from abuses that pure laissez-faire capitalism would have allowed. The National Labor Relations Act was a state action that allowed for collective bargaining of workers. More recently the Consumer Protection Financial Bureau acted as an agent against uncheck capitalist forcing a fair playing field.

I'd probably agree if you changed your word to "frequently" though.
