I don't think the only fix is by stopping loot drops.
And the purpose wouldn't be to prop up the real life cash value of silvers. It would be to prevent hyper-inflation of basically everything.
The cash market is part of the game, whether you like it or not. Wyrom used to participate in it, so I'm sure he's not exactly against it.
You may not like it, but it's only going to get worse unless some kind of effort is taken to find a need for silvers.
