Autonomy over your own body is one thing and you’re right that it’s your own body that you’re destroying but ‘why should you care’ isn’t always in society’s best interests.
The subsequent ramifications on healthcare are a lot deeper and longer lasting than just their body. One more healthy body is one less burden on the healthcare system which in a lot of societies are under a lot of strain, and it’s one more able body contributing to economical / societal advancement. So it is actually a double positive.
