I'd highly recommend the historical fiction "Red Plenty" which followed the trajectory of Academics in the soviet union trying to compute idealized prices - meanwhile administrators, consultants, and realists had to just make the system work.

At one point a quota increase leads a factory to sabotage it's old equipment, so that they may get a new machine to hit the quota. The administrator in charge of approval determines as much - and arranges for a new machine. Unfortunately a pricing reform introduced by the same plan leads to an inability to build the new piece of equipment as equipment was priced by the ton. Requiring the intervention of "well connected" individuals to solve the problem...

Systems adapt - any reform will introduce exploits, and pathologies. To pretend that MMT based central planning yields a different outcome in the long hall is folly.
