Pretty sure existing and newly established businesses have already looked into accepting Bitcoin. many are probably jumping into it and earning quite a bit of profit just because they started accepting. Bitcoiners show their appreciation and buy some things from them (overstock etc).
Hopefully within a year or so there will be more new businesses accepting Bitcoin.
People have been scamming others for hundreds of years, this isn't something exclusive to Bitcoin and it's just as stupid as claiming that Bitcoin enabled terrorists and drug dealers, the only difference is everybody is noticing it more because it's a relatively small market right now.
