Why do I have TWO Library Directories

More information is required, a lot more. For example, what do you consider "questionable"? What problem are you attempting to solve?

Post the crash reports if you think they will be helpful. macOS does not use the backslash character for file names. It is reserved for other purposes.

The screenshots you posted are distorted on the Mac I am using. That might be something with my Mac, or not. To learn how to take a screenshot, edit it if necessary, and subsequently post it to this site, please read the Appendix in Writing an effective Apple Support Communities question.

You actually have three libraries, /System/Library, /Library and /Users/<Home>/Library. This is all perfectly normal

and they should be left alone unless you know what you are doing. Removing or altering the files helix in the libraries especially at the root level could seriously impair the function of your Mac.

As Eau Rouge already stated, there are many Libraries because unix is a multi-user operating system. Not only are there human users, there are processes that are run by "users." All of the users require support files stored where they can access them.

Apple's processes use /System/Library

All users can use /Library

And, individual users have their own Library in their home.

You'll have to be explicit about what you attempted in Terminal as it appears you just don't understand the directory structure and are entering invalid commands. Copy the commands you are running and the output, then paste them into a reply here.

One with lot of questionable items, including the sketchy Extensions I've been trying to get rid of forever but can't.

There is nothing wrong with your Extensions, everybody has them. What leads you to think they are "sketchy"?

I recommend you leave the file system alone if you want to have your Mac continue to operate.

I don't see anything wrong with them. Are you using Safari or another browser?

FWIW, although the screenshot looked normal yesterday the text looks like a condensed font today in both Safari and Firefox. If I click on the image, the image that opens looks normal. Weird.

The backslash character is not used in macOS file names. Its use is reserved for other purposes, such as an an escape character to denote literal use of the subsequent character.

... I'd have to type DVD\ Player.app or use quotations if I wanted to write use a space.

That is correct. The file name for DVD Player.app is DVD Player.app.

I'm not sure how you are getting the results you list using the commands (or part of a command) that you are entering.

Any of the .../DVD Player.app/ commands should result in:

/Applications/DVD: No such file or directory

I don't know of a version of bash that will handle spaces as you indicate. Are you using bash or another shell?

Can you post the full command and results?

Also, the double-slash is unnecessary; subsequent additional slashes are ignored. It only needs one slash as Contents is a sub-directory of the app package folder.

Actually the entire screenshot looks compressed horizontally.
