But that's the difference between buying insurance, which is an actuarial product you buy to guard against unfortunate events, and buying a service or subscription, which is available for your use when you desire to use it.
Let's ask a simple question to determine which is which in the US: because attending your annual checkups reduces your risk of needing expensive treatment, somebody who attends their annual checkups are cheaper to insure. Are there any American insurance plans that effectively pay patients for attending their checkups? Are there any American insurance plans which say, well, your premiums are $1000/month, but if you go to your annual checkup, not only will your checkup be completely covered with no co-pay, but we'll reduce your next 12 monthly premiums to $950/month each?
After all, if it reduces costs for the insurer, then the insurer is motivated to incentivize patients to go, right?
