If your goal is to make your art as ubiquitous as possible, why not?
I also see it as a momentum thing, if I happen to have a viral hit song, I could either drop all my own money and resources trying to keep people's attention or sign to a machine that would help me grow and maintain that momentum and marketplace demand on a larger scale than I ever could independently allowing me to focus 100% of my mindshare on my art? Almost all record labels are subsidiaries of larger entities...that means portability which can lead to potential revenue streams. Of course, none of that is going to come for free. Every system has winners and losers, no different than taking a loan for a private university liberal arts degree, then getting mad when you're on the hook for $100k with no means of paying it back because there's no demand for a history major.
In a perfect world, every artist with a vision could personally finance their own success story, make tons of $$$ and have millions of fans and a long, substantive career while thumbing their nose at the "man". Why exactly hasn't that happened yet? Probably because its much smarter and easier to lose on someone else's dime. Like the saying goes," zero of zero is still zero" (maybe I botched that saying, sorry) Why do you think we have venture capital firms?
Also, the "old" system still has its hold and power and I don't see that changing any time soon. There is a reason why, despite all his indie success, Tech 9ine still can't crack radio, despite having a fanbase that continually supports him, him and his partner lamented this fact in a recent issue of The Source (or XXL, I forgot, but someone should be able to find the article or a reference to it). Why would a successful indie like Strange Arts be concerned about the radio at this stage in the game? Because they know that radio play can possibly mean the difference between a few hundred thousand units sold and a couple million while Tech doesn't have to change a thing about his sound. Unfortunately, you still need a major label marketing budget to crack radio.
