Except it runs into an excess problem. As an example, Berlin - just one city - has 7 professional orchestras. They are supported by the government financially to the tune of 200 million EUR per year. There is a very real opportunity cost here and quite a bit of a wealth transfer to old people at the same time (since the audiences for classical music tend to be on the older side).

You could pump a large part of those resources into supporting other kinds of music and arguably the outcome would be more interesting.
