I'm not opposed to physical care at all. The Medicare Wellness Exam also include a mental health and cognitive evaluation. You get certain words spoken to you, then other distracting events take place. Later you need to recall those words. If you don't, bad news. The doctor tells you to draw a picture of an analog clock based on a time he will state to you. If you can't do that reasonably quickly, or put one of the hands in a wrong place, bad news. And there is more.
These things have nothing to do with physical health or preventive care. If I want to seek cognitive assessment or care, I believe that is my right, and my choice.
Even succeeding at the tests is a slippery slope. Imagine doing 100% on the Wellness Exam for 10 years. Then because of some gradual forgetfulness that is coming on, or other reason, you decide you don't want to do the test any more. In the Government's view, is that refusal, by itself, an admission that you are not up to driving? Or owning a gun? After all, if you did them before and won't do the test now, isn't that proof that you *know* something is wrong and you may be a danger to society?
I have watched our civil liberties get progressively chipped away over the years. Organized all-night long DUI traffic stops using officers, cones, and flares used to be illegal to do. It was considered detainment without probable cause. Then in my community, the police announced they would only do it on New Year's Eve, only on one street with plenty of "escape" lanes if you didn't want to go through. Then it grew to all major holidays. Then the escape lanes went away. Now they seem to be all over the place and are quite intrusive.
The City of Berkeley, CA went one step further. During the organized DUI traffic blockades, where you were detained without probable cause, they also required you to pop your trunk to submit to a weapons search. That got overturned very quickly.
I know exactly how the civil liberties slowly get chipped away. I don't want to hand the government data on my mental or cognitive acuity. Unless I commit a crime or other offense, it is none of their business.
