How does DRK solve any problem for merchants and clients? I have bought items from reputable merchants using Bitcoin. I didn't notice any problems. In fact, every purchase I have made from overstock.com was flawless and immediate. There isn't any problem that needs to be solved.

But instead of embracing Darkcoin I think businesses will just continue to conduct their financial transactions through normal banking channels. Also, overstock.com generates a new btc address for each purchase so as long as businesses didn't just reuse the same address there wouldn't be an issue with being spied upon.
