It is not necessarily what is available that matters. What is scarce can be paramount too. We can see this in our own lives as well. If you skip on sleep to have more time, tiredness then becomes the limiting factor to your productivity, not time. In manufacturing, a bottleneck is a similar concept. A factory process can only move as fast as the slowest step. Likewise, in mathematics we refer to multiplying by zero which is akin to the Law of the Minimum—put a zero at the end of a multiplicative calculation and it cancels out the numbers before it, no matter how high.
