I'm not thinking the youth presidencies should have access to much information: just basic information on who they are called to serve (name, address, birthday, phone, email, and for YM, current priesthood office). This information is available to them if they use the directory or LDS Tools (except for priesthood office and birthday); it's just not in a convenient form. I remember we got lists when I was in YM...just a few years ago

They were helpful. But there weren't so many privacy concerns in those days, so I could see some things making it difficult.

Why not teach the youth the sacred nature of their callings and how they need to keep certain information in confidence? Maybe they'll remember those lessons when they're adults. We have plenty of examples of the Lord trusting youth to do some very important things.
