The disadvantage of points are two fold.

Firstly, there is the inability of the system to absorb the primary side voltage spike from the collapsing secondary field. This causes points to burn and condensors to wear out and open.

Secondly, as the lobes and bushings wear in a point system the dwell angle changes enough to cause preigintion. This results in overheating and engine damage.

So getting rid of the breaker points as a load bearing circuit is advantageous. The rotten location of some distributors notwithstanding. Additionally, a little engineering could develop a solid state voltage amplifier to use a modern ignition control module on a 6-volt car.
Problem is the market is shrinking.
