Decentralization doesn't necessarily imply lower supply of goods, but it does almost certainly result in higher cost of goods (outside of compared to monopolies). That's the cost of market resilience: higher average cost for lower variance over time. Higher cost of goods may result in lower demand and then lower supply, but the causal order is the opposite direction from assuming decentralization means lower supply.
