Is there any value to doing the NAI and DAA browser opt-outs?

Referring to two so-called "self-regulatory organizations," the Digital Advertising Alliance (DAA) and the National Advertising Initiative (NAI). They offer a way to bulk opt out of numerous cookies that serve interest-based ads. Not sure if they actually have any value. For instance, are they still tracking me but simply not serving me ads? That would be a half-assed solution to the problem.

P.S. What about Google's browser extensions to opt out of IBA and Google Analytics?
