That’s the pragmatic solution. The article is about an interesting mathematical puzzle, not actually solving a real problem.
Also, an n-sided die is fair for 2 to n players if you discard rolls above the number of players.

I agree the math problem does not map well to a real problem players are having.
You don't have to buy them to use them. For example I own a baggie of D(4-20) dice but I don't and have never played tabletop RPGs.
This set may end up too expensive for my "i know i'll never use it" budget, but other than that I'd get one.
