> If I’m an adult and identify a risk to my doctor, why shouldn’t a cheap safe and reliable preventative measure not be accessible?
I wouldn’t call it cheap, but it is available unsubsidized. Which makes sense from the perspective of society in terms of cost vs benefits. Your personal income and risk profile may mean spending money on this is worth it to you, but society is just focusing on averages.
You may think it bizarre but consider this logic.
Let’s suppose for the average 12 year old the number works out to 1 million dollars per cancer prevented. But for 60 year olds it’s 100 million dollars prevents a single cancer on average. The difference coming from reduced future partners, prior exposure, and reduced remaining lifespan. (By reduced future partners, I mean most people have partners between the ages of 12 and 60, so a 12 year old is taking those risks plus the risks from partners after 60.)
Now a billionaire may be happy at even 100 million per prevented cancer, but I think the general public would prefer lower premiums/taxes instead. 45 years old isn’t some magic number it’s just somewhere between extremes. Other countries are using much younger ages.
