Many of the people I care to listen to live far enough away from me that to 'actually sit down, and physically listen to them' is a multi-day endeavor.
Not to mention either expensive (whether in terms of fuel for private transportation or fare for public/quasi-private transportation), hazardous (hitchhiking, "on a freight train leaving town / not knowin' where I'm bound", etc.), or way more than a multi-day endeavor (walking/bicycling/etc.).
