That would be pretty limiting relative to projects unless they are served well with preconceived thicknesses proportionally. A good example that came early in my woodworking endeavors was Norm Abram's Shaker Wall Clock project. Proportionally, it required thicknesses like 5/16" and 9/16", for example. So while I will agree that many folks can easily work with S3S and S4S material for many kinds of projects, having a thickness planer opens up a lot of opportunity for projects that will be a lot more satisfying when they are not built from 3/4" and other "standard" thicknesses. And, of course, if one wants to work in metric...which is a perfectly valid choice...S4S and S3S isn't going to happen in most of North America. This is just a devil's advocate think because you are not wrong, either.
