Most people don't own an Atlas anymore. In the public consciousness Google Maps is the world map. If choice of map projection is important anywhere (which is debatable), it's important on Google Maps.
And remember: you can always fail over to Mercator.
Map projections are part of the technological infrastructure of the world. Most people shouldn't have to worry, but someone needs to. What about calculating missile range? Or designing a tunnel that needs to be accurate to 1cm. Are your GPS surveys out by 30cm because you used a system that ignores continental drift. Or placing an oil rig in the wrong place in the sea due to a poor projection choice.
