As said the licences are none transferable, but all your files are yours and certainly can be distributed to anyone.
And of course if you leave them your DAW computer and the password to fire it up they can certainly carry on from where you left off and finish your works in progress.
There is nothing illegal that I see about sharing the software on the computer. It's not like I have to tell clients.. "Stay away from the DAW! If you touch that keyboard I'll go to jail!"
They would just not be able to access your account and updates. They would need a new licence for that.
