It is an interesting way to think about the NEP. I would say it was analogous to western capitalist economies experimenting with government control, except that most western governments had already exercised a great deal of control over industrial growth throughout the nineteenth century, so it was perhaps less of a departure for them than the NEP was for Lenin. Basically, it was just accepting what had already happened. We forget today what the Bolsheviks learned in the wake of the Civil War- that when peasants rallied to Bolsheviks promising "peace, land, and bread" they meant that they wanted to own land, and in the wake of the war, they took it. Tragically, the NEP contributed to the already rising kulak class that were completely annihilated by Stalin.
