Very good point: unlike humans, a sea-urchin's grandma doesnt bake cakes for her grandkids.
I guess see the 'long life' / 'no menopause' pair as an inseparable chicken-and-egg problem.
So, is it:
a) they are able to reproduce at advanced ages, and this provides evolutionary pressure to increase their lifespan, OR
b) their makeup somehow allows for them to potentially reach an advanced age, and this provides evolutionary incentive to increase the hardwired limit on the length of their reproductive careers
I undestood your argument as a), I wonder if you think the reverse (ie. b) is also possible.
