While the spark does go through the plug to ground (the block), it has to get back to the coil somehow. If there is not a complete path from the coil, to the plug, and back to the coil, it just can't work. If the coil is arranged so that the path is through the points, it will arc across them. The path through the battery is the correct one, as the battery is a fairly low impedance and will pass the very low current that the coil puts out no problem.
