I agree totally except on the opera thing as I think it does something unique in using music to provide a commentary on what is being sung. At its best you get a sense of character motivation and / or sub conscious streams that can't be entirely expressed in lyrics and melody alone.
Whenever I go to the Barbican or RFH or ENO the hall is almost always rammed and not just with people acting out some class imperative. It's not Henley or Cowes by other means. A lot of people still seem to want the symphonic ocean of sound experience. ROH has more of that and also seems to host more of the corporate entertainment types. I would hate to see the ENO go down necause it does provide access to an art form that I still believe in. Obviously other opinions on that are available!
