Ignorance and inability to appreciate art. Many of the yes voters have arguments along the line of claiming art is immaterial and redundant in today's society and does little for human advancement and mankind.
Often people feel that science and technology are the main or the only factor that contributes to the advancement of society. But what they don't seem to understand is that without art science and technology would be equally pointless. There has to be a balance between both. Looking at man's survival and development from a holistic point of view, BOTH science and arts are equally important and carry the same amount of weight.
Science can cure man physically, while arts cure us spiritually.
Even if a dying person receives physical treatment, but lacks the will and soul to survive, he or she has a high chance of death through recurring or other illnesses, vice versa, there are many cases of people surviving miraculously through fatal diseases with a positive mindset and inspiration through the arts.
Sciences and technology develop our society, while arts improve the quality of our lives. They must go hand in hand. The reason why so many people disregard art, claiming it to be pointless and a waste of time, is because they fail to appreciate it. They lack the cognitive ability to express through art and hence do not see the point of it.
Our "civilized" society today focuses too much on materialistic values and goals, thus giving many the impression of that immaterialistic ideals and factors are worthless. But truly, a man cannot become successful with science alone. Everyone is in contact with the arts, be it the music we listen to, the architecture we see on our way to work every morning. Even the most renowned scientist cannot say that he does not require the presence of art to further his achievements.
Without art, as an "indirect" factor, science as a direct factor cannot come into play. A truly "modern" and "civilized" society should understand the fact that arts are equally important as the science. Similar to a vehicle, the tyres are the sciences and engineering while the fuel is the arts. Lack of either rends the vehicle unable to function.
A civilized man should not merely develop intellectually but also spiritually. A successful man does not merely have materialistic achievements, but also his sense of fulfilment, spiritual nourishment through his appreciation of arts. Both sciences and the arts should go hand in hand. We survive on science, but we live on art. I may be a realist, but I believe that even though we may live a long, "successful" live through science and technology, but without art, it is truly not a life worth living.
