Except it was done in droves by the shady third party sites sad fact is the supply and demand are going to be there no matter what. Difference is
1. Safer lil Timmy isn't getting his identity stolen or scammed cause he wanted to buy gold
2. Better for Blizz (money goes to them)
3. Better for players allows them to literally go F2P if they so choose
The big issue is the trade chat and group finder spam....
