Greed is as normal and natural as sex. If there is no legitimate, productive outlet for it, it finds illegitimate and unproductive outlets. This is IMHO who communist states turn into mafia states: the mafia becomes the outlet. Part of adapting to the change is going to be building legitimate profit avenues into systems so that the profit motive can find productive channels.
All the old systems had no channel at all for profit making, so it made it's own in the form of spam and similar.

The reason that former communist countries like Russia became oligarchies (what I think you might mean by mafia state) is because people with significant power in the previous communist system seized control of huge state assets during the disorder that accompanied the system's collapse, and in doing so took ownership of large pieces of the economy. Even under communism, power was closely held among a in-group, and that stayed the same afterward.
The oligarchy didn't emerge because average people were bored and provided for, didn't know what to do with themselves, and therefore decided to set up illegitimate enterprises.
Also, plenty of people in capitalist countries set up illegitimate enterprises like financial frauds and consumer scams of all sorts (remember 2008?), and capitalist societies have their own oligarchs - though we call them plutocrats instead.
It doesn't feel that natural. I think we should stop resorting to human nature when something fits our mood. Violence is natural but we try to stifle it because it haa few benefits. Greed should be the same. I don't think our current worship of money is healthy for the future - if you believe what they say about climate change atleast.
