Windows has that feature now. It's surprisingly effective, and is smart enough to preserve, for the most part, user files as well.
A major reason that CD's stopped being used is the straight up lack of optical drives on modern computers. In most cases these days you specifically need to look for a device that includes optical or other physical media that is not USB.
Given the ubiquity of internet access in most markets where computers are sold (even in developing countries), it is very reasonable to expect that even as a last ditch, the user will be able to connect to the internet on a tethered cell phone, and this is reflected by the fact that on consumer OS you can specify that a connection is metered.
