Actually, all of life is contingent on death, not just the good in it. We sustain ourselves by consuming other dead beings, be it animals, plants, fungi, etc. They themselves lived thanks to the death of other beings and so on.

The lego analogy expresses the fact that we are not different from these other beings, and that we too must die so that life can continue. The death of an individual in this chain is always painful, but as part of the whole, it is just as it should be.

That's not what I meant. The good in life is not inherently contingent on death.
