I get it this game has Crafters as Classes so there will be a lot of items in the market.
But why not add more options to remove items from the game rather then restrict the options even further?

Bound gear is usually vendored (thus effectively removed from the economy) or sharded (via reverse engineering, de-synth, disenchanting). I guess this is more a way to prevent market saturation, which does happen in games with unrestricted resale.
