My argument leans heavily in the fact that electronically magnifying a painting does not work for most, whereas amplified voices do. Otherwise everyone can just Google the paintings right? The magic is seeing it in real life. Which has practical limitations hampering the business case.
And everyone can also listen to music at home, yet many go to concerts instead, and many say that hearing a band performed unplugged adds an extra layer of authenticity and intimacy to the sound.
Yes, exactly. People can listen music at home, and also see pictures of paintings at home. Yet people do go to digitally scaled events of musicians, while they don't go to digitally scaled events of paintings. Why that is, I tried to explain in my previous post. Your argument regarding authenticity of unplugged artists applies only to a fraction of people.
