Why? Basically because it’s how the creative arts industry has set itself up to work in the 21st century. It’s very much a DIY scene. Be it music - not just bands either, but also orchestras, composers, DJs, producers, tour personnel - including roadies, lighting, sound, trucking, there’s also theatre, dance and TV production. It’s also a fantastic and highly rewarding experience. For many it’s an important revenue stream.
