There are dozens of highly-functioning economies in the world that barely use English at all. I just got back from a holiday in France, which has its own fighter jets, nuclear weapons and aircraft carriers, yet only speaks English in jobs that are directly related to foreign communications. A random person you meet on the street will be very unlikely to understand you if you speak English to them.

It's a pipe dream to expect an average French person to enjoy art in its native language, and as a businessperson you will limit you market by doing this.

Granted, the English-speaking world is currently the world leader in technological capability and economic power, but it's quite myopic to assume that this makes everyone else irrelevant.
