The villagers have obviously never heard of work management. When building a hut, for instance, they will make long trips to the wood pile or the boulders each time. Wouldn't it be more efficient if the builders stockpiled the supplies in a central location much nearer and then took their building supplies from there? They could be used on these stockpiling trips in periods when there is no actual building work going on, and thus gain experince.

Similarly, the food bin, although close to the crops, is quite some distance from the coconuts and the ocean so farmers also have a long walk back and forth.
