I agree @sugar.

Ebay is moving towards a system where there is more seller accountability along the chain from initial purchase through to delivery and buyer satisfaction as there are so many other platforms for people to choose from these days instead of Ebay. Want clothes? Use Depop or Poshmark. Want unique? Go to Etsy. 

Keeping buyers satisfied here is a means of containing them within the Ebay ecosystem. Adding tracking and expecting a high seller standard shouldn't even be an issue. Gosh, if the OP thinks Ebay is hard, try be a seller on Amazon where the benchmarks are much higher.
