Then why do ignition contact breakers have capacitors across them?

The horn button is a simple on-off contact. As the spark arcs across
the gap, it causes oxidation and pitting at the surface. I can't see
what relevance insulation has to this as the arc is between the two
contacts which, er, contact each other, except that the insulation
would be more insulating than the air gap.
