Imagine that someone said:

An obvious observation would be that it is dreadfully difficult to produce the expected product of a sawmill without tools to cut or sand or otherwise shape the wood into the desired shapes.
One might also notice that while a sawmill with no wood to work on will not produce any output, a sawmill with wood but without woodworking tools is vanishingly unlikely to produce any output... and any it does manage to produce is not going to be good enough for any real industrial purpose.
