"Paste item" missing from finder's right click menu

As very correctly mentioned by contributor @Luis S the Top Level of the computer is housed in a Separate Volume Sealed and Read Only Volume on this computer.

It can not be opened by the User ( you or I ) and / or Third Party " Bad Actor " Software to modify, remove or otherwise have any director or indirect access to this Volume.

This is by Apple Design in Big Sur and Monterey

The only Entity that can alter this volume is Apple and usually only happens during an update or Upgrade.

You are welcome and thank you too 🇨🇦

But the real credit originated from colleague Luis S who spotted the issue

Do come back to the Apple Support Communities ( ASC )  in the future, if / or when additional questions may arise

Hi, in macOS Monterey, when you copied the file, you need to right-click on a blank space in the finder to see the paste button(don't right-click on another file). The paste button is beneath the "New Folder" button.

Moreover, a more convenient way of copying and pasting files: select the file you want to copy and command+c, then paste it by command+v(just like copying and pasting text).

No bug.

Since you cannot write anything to this location, you cannot paste there.

In Big Sur and Monterey, the top level of your drive is mounted as a sealed read only volume, which is a very good thing.

Sorry but in Monterey in Mac Mini M1 running Monterey 12.4 the are No Additional Partitions on the drive beyond the below copy and Paste from Terminal.

There are Volumes and No Partitions - unless the user has pre-partitioned the internal drive otherwise

So where is the Partition appearing ?
