The Canon EF 50mm f/1.2 L USM Lens is going to be purchased by those who want the best image quality they can get from f/1.2 to f/2, by those needing a more-pleasing background blur quality than the other two 50s deliver, by those requiring the least amount of lens flare in their results or by those who need/want the best quality (build) lens they can get. I can’t say that the Canon EF 50mm f/1.2 L USM Lens is a good value, but I do think it is worth the price to serious photographers who need what it can deliver.
