My response to the intrinsic argument is something more like this:

Very few things have actual intrinsic value. Sunlight and water are some of the only things on earth that have naturally-occurring value to all living things because they wouldn’t survive without it. Food (used generally) could be considered to have intrinsic value for the same reason. Outside of that, each individual human values things differently, so the value each individual human gives something depends on its usefulness to them. Some people may consider gold valuable as a money, some may find it valuable in electronics, others may not find it valuable at all.
