The main problem is: it is still reliant on money and economic growth. If ever the GDP tops out or enters yet another boom-and-bust cycle the whole plan will result in a modern capitalist collapse due to the lack of opportunities for growth. Also, with this model it does not address wage or the abolition of poverty, or worker's rights. Unfortunately we still need a solution to the capitalist crisis in the form of production regulated for people rather than profit. Profit is simply not a sustainable form of economy any longer.
