I have no issue with lossy compression; but things like 4:2:0 aren't really typical lossy compression. It's like calling resizing an image to half its resolution "compression". Also lossless compression can reduce plenty of "wasted" bits already (see: png vs bmp).

But they are ! Like other lossy forms of compression, chroma subsampling takes advantage of the human visual system's lower acuity for color differences than for luminance.
