I’d give the kid an allowance, where they can earn money by doing extra chores and learning more etc. and let them make in-game purchases with this money. Either they decide themselves that it’s worth saving the money for better things, or they develop discipline through extra work and learning, which presumably means they can rein in the addiction when they grow up.
