Well, you can try that, Bud, but in my experience with W7-W10; deleting library folders, assuming you can do so, is messing with the apps portion of the windows kernel in the OS itself. System instability often results, even using the many hundreds of hacks I've seen around on the Internet, YouTube, etc. Inevitably, when a Customer brings me in computer that has 1 or all 4 of the system library folders removed or renamed, I gave up repairing those long ago.
Even, if you repair it, some people tell you they only have 1 computer with locations in the libraries but as Norway mentioned they can be linked to multiple locations on other home devices in your home network, such as tablets, laptops, smartphones, kindles, etc. not to mention domain-network locations outside of your home such as your work (via VPN) or University networks. When people do work on their home computers, they often will intermix their home and business uses, and never learn to separate those functions onto different computers.
So, if for example one of my friends who is a professional photographer and years ago he attempted to delete all his library folders (for whatever weird reason), his W7 became useless, as he could no longer access secure network folders where he "dropboxed" his photos for possible publication, and received contract and model release forms and that sort of stuff back from his publishers. He had to rebuild his entire PC from scratch, and then reconnect to those server folder locations and in several instances it took him days of phone calls to his publishers Tech Support or IT people to reconstruct all those links.
If people only had there PCs for 6 months before tossing them in the trash, this wouldn't be a problem, but people fill up their computers with all kinds of stuff both personal and work and then start to try and streamline then because they think they are getting too much "junk" on them or it's slowing down their performance etc. etc. when you have 5 years or even 10 years of your life on a computer and start tweaking it, it can cause havoc and not in any small inconvenient way if you know what I mean.
My 2 cents.
