I think a lot of your examples are a little bit misguided, a case of not understanding the reasoning behind laws. Sometimes, things are illegible because we lack the correct perspective, not because they're fundamentally wrong.
For example, at least in some parts of the United States (Texas is the one I'm familiar with, but others might exist), it is legal for minors to consume alcohol, even in restaurants, with parental supervision (https://alcoholpolicy.niaaa.nih.gov/APIS_State_Profile.html?...).
The reason children can drive cars relatively young in the United States has several factors, but one of the big ones is the distance between places. I had a roommate who started driving to school when he was 14 or 15 because it was the only way for him to efficiently get to his school, which was still a 25 minute drive. There was some sort of special licensing in Iowa for children that young to drive to and from school unsupervised, because it wasn't efficient to try to bus everyone in. Now, you might still think this is a bad law, but it's not like they just made up a driving age for fun. The social, economic, and political reality of certain areas of the United States makes driving far more valuable than in many other places in the world, simply because practical transportation alternatives do not exist.
For example, if you see a woman driving in Saudi Arabia, it goes against the law, but is not a crime.
Another example, in the US having a kid drinking wine goes against the law. As a kid in Spain and France I drunk a glass of wine in all meals, like the rest of my family and it is very healthy.
You get used to the rules in your country, but this does not mean that the laws are good. For instance a foreigner going into the US will probably consider barbaric the tradition of circumcising kids when they are born( I thought it myself), but locals rationalize and defend it(like locals in Saudi Arabia do with women driving).
A kid can drive a car but not drink a glass of wine? Utter non sense, but real.
