What Ol'George said.

For some of the reasons he said and others. My reason. If any of that system fails you are SOL maybe in the middle of cutting grass.. Points are super simple and you can just about always get em going even when quite worn out. Points are available at most parts stores. This is the same reason they were used in boats forever. They rarely keep you from running for more than a few minutes if you know how to adjust and clean them.
