Like musical tours?

Alright, so I guess we should just visit local concerts that we can only access by bus/train, since it's putting less strain on the environment. All bands play in the same area, or at least in the same country (state, if you're thinking big, like the US or similarly sized countries).

But there's NO way people from other states/countries wouldn't want to visit their concert at least once. So every single concert, you would have people travel to your area from different countries, probably taking the plane. So now, instead of one band flying to places, you get dozens of people taking flights from various countries. Every single concert.

It feels a bit like ordering online, where there is only one guy in a van delivering stuff to dozens of households instead of those households driving to the brick-and-mortar shop one by one.

I'm not saying the current system is optimal. But I really wonder how else we could solve this particular problem.
