Since digital zoom produces inferior image quality why not have only optical zoom in digital cameras?

since digital cameras at the simpler end have to compete on price, makers tend to use digizoom first.A zoom lens is a bit dearer. If you only use a bit of digizoom results can be fair, but are better if you have LOADS of pixels to start with.And the 'usual' alteration in perspectives from tele to wide don't happen in digital-all looks the same.
