Actually, the point of the linked article was that irrelevant alternatives aren’t. Rather, they reveal information about relative strengths of preferences IF, as Arrow’s Theorem’s assumes, you are restricted to voting methods involving ordinal ranking of the options.
Therefore, you can avoid the claimed problems by being able to express the magnitude of your preference, not just its ranking against others, which is the idea proposed here.
