>I think it is common for a child of his age to follow his parents' instructions.

True, but the parent should be making these decisions as a advocate for the child, and not looking at the child as a resource for their own benefit.

I get that this is not how it's always been done, but if you are lucky enough to live in a time and place where we don't need the labor of our direct children to survive (New Jersey 2021 counts IMO), then you have a duty to act (as best you can) as the child would if they had a fully developed sense of reason and self expression.

Personally, I would be thrilled if my father had supported my development into a grand master.
