Critique of coin?

[Flying Purple People Eater]

One of my good friends is a liberal who has misread marx and now identifies as a 'communist' (he thinks that the abolition of private property means the de-privatisation of industry and the revival of public industry and nationalism), and has consistently berated me with lofty arguments of ultra-keynesianism where taking from 'the rich' and throwing money at poor areas or positions of inequality (institutional racism and whatnot) will solve everyone's problems.

Does anyone have a couple of good criticisms on the monetary system, most notably being why it inevitably centralises and how 'equalising' the money in global economics is detrimental? I understand it's flaws vaguely but am terrible at articulating said flaws with evidence to match them.

So, you got any?

Deprivatization does not stop the crises of capital. It still retains disorganized and anarchic production.
