This is also a typical approach from the chefs I know: they don't care about precision in most recipes (eg. dishes like soups, or pasta, or salads...), but then sometimes there are dishes where precision is absolutely crucial, and baking is one place where precision is really important.
With sourdough, if you don't measure, you may still get good results, but you will have to babysit the dough and try to figure out when it's ready by checking frequently. Some people can afford it time-wise, and to some this would be prohibitively inconvenient.
