The "green" material one puts on the compost is, in actuality, mostly water, and although it does indeed have more nitrogen and other nutrients than do the brown materials, it is still not exactly an ideal source of them. Besides adding what nutrients it can, it's main purpose is to add water and to provide a soft material that will fill gaps between harder materials. Neither of those things are a problem when the decomposition is taking place underground, however, as the surrounding soil fills both of those roles. All that really matters is nutrient (or more specifically, nitrogen) levels.
Home compost is made the way it is not because it is the ideal method (it's far from it), but because it is an efficient way of processing the materials used. A garden or allotment generates a lot of waste, and so composting that gets rid of that waste and provides a free source of compost at the same time.
The ideal method of composting, it terms of both speed of composting and quality of the finished product (both texture and nutrient content) involves the hot composting of large quantities of woody materials, as finely shredded as possible, mixed with something high in nitrogen and water retentive, such as animal manure.
