anyone begging or grandstanding for trading again is basically just trying to make it like diablo 2 and PoE which both have real money issues and micro-economies of people farming (which opens up exploitation) and selling of digital goods for real money on third party websites.
The answer to this is the 2 hour trading window in game with the players who were present when the item dropped.
Trying to beg or make some case to go back to the old trading is basically just you trying to get real money involved.
