An argument that is not against specializing in a single good in the real world is that specialization in a single good makes dumping easier and more effective.
If a country specializes in a single good, less waste will be produced and it can be dumped easily at one place and can be used or recycled more easily than to dump several different kinds of goods as they will need different technologies and to segregate them will be a hard job to do.
