The image unfortunately does not tell us if the book was used for promotional purposes within the classroom, whether this is a one-off or a regular presence in that school/more schools, whether is down to a nerdy teachers interest, or whatever. Context matters ...
There are classes that work just like book clubs, they pick a book and everyone either has to do a study on them by next week or it's analyzed during schools hours, it depends on what is based foreign literature or history or even arts.
I assume by the age of the kids that this was done during the technical classes that are still mandatory in some primary schools, as there is no mandatory economics study before high school yet. Highly probably that it was a private school, those have a more flexible approach and can tech a few things outside the normal curriculum
My personal opinion is that it is unnecessary to expose children to such information, because it is simply too early for them to be burdened with it. It is quite one thing to read a book, and quite another to understand what it is all about - and it is even worse if the person who needs to clarify these things is not an expert at it. I don't know how the book is conceived and how the teachers are trained, but from the fact that someone lives in ignorance, the worse thing can only be that they learned something completely wrong.
Don't worry, it's a 20 pages illustrated book that is about the basics, nothing complicated.
The only problem with it might be that it kind of implies that
everything other than bitcoin and decentralization is bad...apart from gold.
