(And actually using it as a currency, but don't tell anybody :p)
Not really sure what you are talking about or why you would make such an assertion.
I already do quite a few legitimate business transactions every month using bitcoins.
Yesterday I talked with one of my suppliers, who experimented with mining a year ago, and will be converting all our trade to bitcoins (easily $500+/month). He has an independent contractor who does computer programming in Canada whose Paypal account was banned so it is hard to get payments up there to him. Guess what my supplier is going to start using to pay his contractor? Bitcoin.
With the new BitInstant credit/debit card that will make it so easy to phase in and out of bitcoins and fiat we can pretty easily begin demanding all our independent contractors to accept bitcoins. Of course, it will start off with a bonus, around 5 BTC, but after everyone has their BitInstant credit/debit cards working then it will switch.
Don't take bitcoin for the entire gig/salary? You're fired. In this economy, there are plenty of people out there looking for work.
