It's a shame for the people who need transplants, but reducing accidents is overall an improvement. Fewer people are dying overall. If we were approaching this from the opposite direction, nobody would suggest that increasing the number of cars on the road would be good because it would increase the pool of organ donors.

The bigger issue is buried in the middle of the article: we lost out on possible transplants because of lack of COVID-19 tests. There's no upside to that.
