There is a difference between having something and then losing it vs not having it yet. If you get a license to do a thing you should be able to keep doing it until you are deemed incapable and that will vary between people.
Also, plenty of children those ages drive on private property, especially farms. There are kids doing backflip jumps on dirt bikes at those ages. Many of them are likely safer to be driving than others who are of "prime" age. I drove with a 30yo who terrified me with his dangerous lack of skill.
People are variable in capacity and skill. The bureaucracy finds it more manageable to put policy in place than to determine individual skill.

I disagree. The reason for the policy would be the same.
Probability of person of age x causing collision is too high.

Yes, of course. Testing every single person all the time can get costly, and it may or may not be deemed worthwhile by a society (or whatever government leader). Obviously, when people are young, their faculties are getting better, so testing once is not unreasonable.
But at advanced ages, faculties can degrade, and degrade at varying rates. For this scenario specifically, maybe it is not onerous to sufficiently test 90+ year olds that want to fly, since there are so few.
However, since an airplane crash in an urban area has a high likelihood of causing damage to others, society does have an interest in controlling who is in the pilot's seat.
