Points and condenser are throw away consumables, just like spark plugs, tires, wiper blades, etc.....
The other components "should" last the life of a vehicle, save relays, solenoids, or other things that have moving parts. Those parts are subject to wear and vibration. They are non-serviceable (you don't lube or adjust them) so they have a more finite life span. Heck, in the old days you could pull a relay apart, clean the contacts, and adjust the gap just like ignition points. Now they are usually sealed in black plastic boxes with epoxy resin. Some relays are totally electronic so they have no moving parts to adjust, even if you could get into them.
