A poor uneducated man in a remote village is suffering from the same anxieties as a billionaire in manhattan. Its common to all of humanity.
Personally I have never liked working in libraries though I do enjoy browsing the shelves. University libraries are a distracting environment if you are even slightly aware of the hectic activity and volume of material that's going on around you/stored on the shelves.
What do you know about crops, anyway? Is that just some sort of rhetorical device?
edit: also, the idea that it wasn't critical for people a few hundred years ago to complete their education, whether it was in a library or in an apprenticeship, is nonsense.
Its just so weird to me that people worry about the library. Its a building full of information and people whose job it is to help you find that information as quickly and painlessly as possible.
This feels like a general social anxiety issue (not being able to ask for help) than an issue of libraries themselves being particularly scary.
Aside: I don't know what the deal with your first paragraph is. Its clearly an emotional appeal and doesn't make any sense. No one 'fails' at the library. The library is not going to make you fail university, whether or not you use it. As for the custody issue, I have no comment other than there are many steps between being bad afraid of the library and losing your children.
A few hundred years ago and your worries would be related to your crop failing or you know, something even remotely troubling in any way.
People need to take a step back, take a chill pill, and be grateful for the immense privilege and resources they have rather than collapsing into balls of anxiety all the time.
