Touching another person is widely considered an intimate act and most of the general mainstream today are only intimate (physically, or emotionally) with their romantic partner. Broadly speaking we've lost emotional intimacy with close friends and small groups that we've had in the past.
So with that, what is the incentive for the artist to create? He can't sell his work. He can't distribute his work. Touch-based art is highly dis-incentivized in our modern western culture.
