 One reason why graduate students, postdocs, young faculty should really seriously consider their data management plans and take advantage of the fact that you're forced to think about them has to do with making your data durable into the future and the format durable. As I mentioned earlier, I have data on all sorts of devices from punch cards through hard drives that are hooked up to my desktop computer, but they're no longer retrievable. I can't take my magnetic disc or punch cards and retrieve those data anymore, even if I want to use them, let alone to give them to other researchers to use. So it makes your data durable and something that you can use into the future.
