I think it's a great idea, there's far too many businesses that exploit employees by labelling them contractors.
Of course, idea and execution are two very different things.
In NZ, it's often found in courier companies and telecommunications, where you're an owner-operator! Except you have to do what the company you work for says, when they say, and you have to provide all your own equipment, and of course, pay for your own sick leave, accident insurance and holiday pay. And no you can't work for a competitor, are you nuts?
At one point our tax department started cracking down on this, then stopped, I'm not sure why. But it needs to be done.
And let's not even discuss the infamous Hobbit law, where a right leaning government passed legislation under urgency to make all film industry employees contractors, with no rights to unionise, to keep Peter Jackson (he can get the Sir back when he redeems himself in my mind) and Warner Brothers happy after Jackson's Weta Studios lost an Employment Court case brought by a "contractor" who they very vigorously treated as an employee.
