Create folder in root directory using extendscript

I can make a folder in the System/Users directory on OSX Mojave by adding a parent, but I have to give the Users folder Read/Write permissions or the folder will not be created

//create a new folder in the System/Users folder
var f = new Folder(Folder.desktop.parent.parent + "/new_folder")
f.create();

Also here is the Folder API page which includes shortcuts to common folders—you can back out of these folders using .parent, but you do need permission:

Some examples:

$.writeln("User Desktop: " + Folder.desktop)
//~/Desktop

$.writeln("System Application Support Folder: " + Folder.appData.fsName)
//System Application Folder: /Library/Application Support

$.writeln("User Application Support Folder: " + Folder.userData.fsName)
//User Application Support Folder: ~/Library/Application Support

$.writeln("Target Application Folder: " + Folder.appPackage.fsName)
//Applications/Adobe InDesign 2020/Adobe%20InDesign 2020.app

$.writeln("Documents Folder: " + Folder.myDocuments)

$.writeln("System Folder: " + Folder.system)
//System Folder: /System

var dt = Folder.desktop
$.writeln("Full Destop Path: " + dt.relativeURI)
//Full Destop Path: /Users/fishercat/Desktop

var uas = Folder.userData
$.writeln("Full Destop Path: " + uas.parent)

var CC = File(Folder.desktop.parent.parent + "/Creative Cloud Files")
$.writeln("CCF Folder: " + CC);
