Why using $ symbol to represent English is less correct than using the US flag?

If you have only one version per language, just show the flags side by side. UK/US/AU/NZ for english, DE/AT/CH for German, etc.
On the other hand € stands for 20+ languages and $ means USD, NZD, CAD, many kinds of Peso and many other types of dollar.
And this doesn’t affect just some "obscure" languages. For instance, what flag would you use for Arabic, an official UN language? What language does a flag of India, most populous language stand for?
How many flags would you use for Spanish? French?
