your thinking of electricity. The force of gravity only pulls downward. If it were to take the easiest path, that would mean things would have to move laterally to find the easiest path. How does gravity do that?
Your own everyday life experience should tell you this. If you drop a bowling ball on the top of a table, the path of least resistance would be around the table, not through it...but is this what the bowling ball does? No. It falls directly on the table, which is not the path of least resistance, but the direct path downward.
