Who is "the company" in an economic system of infinite middlemen? It would be an interesting way to drive a final stake into the heart of brick and mortar retail; if everything is shipped FROM China for nearly free but shipping TO China costs $25/pound then very rapidly the only way to buy anything will be AliExpress. Remember, "take back" doesn't mean much. Accepts postal delivery? We already have infrastructure for that.
