On one other hand, a lot of fine items cost lots, more wealth than most casual players would find (without selling items themselves).

I don't mind the existing way to acquire items. Contact a person, visit hideout, trade.
But for me to trade to Buy POE Orbs items, it's too cumbersome and intrusive. I don't wish to spend my short time trading.

I wish to actually play Cheap POE Items the overall game. And GGG sometimes appears to forget that!

The Xbox version clearly shows that GGG's vision of trade is totally twisted. It's making trade difficult just to produce it difficult, without actually thinking regarding the user experience!
