The effectiveness of economic planning

So I’ve been debating with a ton of Anarcho-Syndicalist friends of mine. In an planned economy, its ensured that the distribution of goods are reallocated property and usefully, because each according to his need according to his ability. Yeah we have all heard that before, but what exactly stops people from working in a planned economy? Why won’t someone just sit on their ass?

I propose this problem by a famous quote.

Have we not heard the same fears expressed twice? By the anti-abolitionists in America before Negro emancipation, and by the Russian nobility before the liberation of the serfs? “Without the whip the Negro will not work,” said the anti-abolitionist. “Free from their master’s supervision the serfs will leave the fields uncultivated,” said the Russian serf-owners. It was the refrain of the French noblemen in 1789, the refrain of the Middle Ages, a refrain as old as the world, and we shall hear it every time there is a question of sweeping away an injustice. And each time actual facts give it the lie. The liberated peasant of 1792 ploughed with a wild energy unknown to his ancestors, the emancipated Negro works more than his fathers, and the Russian peasant, after having honoured the honeymoon of his emancipation by celebrating Fridays as well as Sundays, has taken up work with as much eagerness as his liberation was the more complete. There, where the soil is his, he works desperately; that is the exact word for it. The anti-abolitionist refrain can be of value to slave-owners; as to the slaves themselves, they know what it is worth, as they know its motive.- Peter Kropotkin

I’m not an advocate of Socialism, just to make things clear, I am an Ancap by all means. However, the intellectual fallacy of LTV is still tripping theorists.
