Perhaps the US can use this as a worldwide strength. Good standards are very powerful.

I'm from NZ and because we import everything, we follow frequency/power/encoding regulations from elsewhere.

Aside: NZ has different plugs but I sure would like to avoid those exploding wallwarts. The last one splattered molten metal and broke the screen of my phone.

Dealing with faulty devices due to communications failures is also expensive (or impossible to diagnose/fix) so standards can help avoid that.
