I know I'm joining a relatively old thread, but just want to say I've had my User account on an external drive for many years. Same main reason as anyone else: data accumulated over many years but still wanted has always been too much for my System drive. Apart from occasional issues migrating to new hardware, it has always worked very well. It is also co9nvenient to separate my base system from all my data.
The reason it's a current issue for me is that I am only now thinking about starting to use iCloud Drive for my data. I've been a Google Drive user for a long time but I want to change. So how iCloud Drive fits with an external user Volume was my concern. DaveF's posts have reassured me and now even AI Overview is getting it right.
