DNT was a terribly flawed idea anyway.
If you don't want to be tracked — just don't allow to track yourself. Make your digital fingerprint as indistinguishable as possible and don't persist anything for any longer that's required to work.

And some fingerprinting issues that can't be solved by lone users could be solved by browser vendors. Let's at least start by doing something with those overlong User-Agent headers. And, say, limiting JavaScript capabilities on introspecting the environment.
For another thing, these two measures would only force the trackers to switch to other fingerprinting mechanisms that are harder to turn off (ETags, canvas 2d/3d fingerprinting, CSS fingerprinting, etc.), so I don't think this would achieve what you hope.
And those were just the examples. Sure, the trackers will switch. ETags and CSS fingerprinting and any other tracking methods can be worked around too. We just have to start value privacy a bit more than dancing bunnies.
(But, sure thing, users want dancing bunnies, not privacy)
