>Why make a green bikeshed when there's already a red bikeshed?

Because then you have two bikesheds. An important aspect of the fact that the bikeshed exists, as a separate entity not integrated with the house, is that you can choose a different one. Specifically, the one that's already painted the way you want.

Maybe you don't think this is a feature in your current circumstance. Others do, which is why it persists.
