Isn’t that a bit like saying the problem in medicine is dying, and other things like heart disease, cancer, etc. aren’t really problems for the patients, as death is the only real problem?
if you had cancer but experienced no symptoms, died in a car crash at age 95, and the cancer wasn't discovered until your autopsy, would you say it was a problem?
Of course it was a problem. If a person has diabetes but then they get shot to death, that doesn't make the diabetes irrelevant.
If 40% of people walking on the earth got cancer today, and it was asymptomatic, it would definitely be a problem, even if nobody saw it as their personal problem in this moment.
