The value of teaching Thomson's plum pudding model of the atom is to understand the evolution of ideas. It also helps the young minds understand that solving problems is often messy and we have to revisit our understanding of scientific models as new facts emerge. It might be obvious to you but the young students would feel that solutions would come in a single shot. Ideally if the students have strong basics 20th and 21st century physics should be tried by the students themselves.
