How about formatting your flash drive as FAT and use it everywhere
without ACL mess?
Alternativly you might be able to achieve this with cunning DeviceKit
/ PolicyKit rules.
I don't see how this can be useful as FUSE because it will be one more
hurdle to jump.
Also I don't understand how can you prove that this flash drive with
this random UID is actually yours on a new machine? Surely that would
still require root access to add yourself to your new FUSE config.

The purpose of this would be that if I have a USB stick formatted with ext4 and I copy files to it at my Linux terminal at home, I would be able to access these files from my terminal at work.

Of course that as long as you are a super-user, you can always chown them to your user in the local terminal and all is well. However, you would have the same exact problem when returning to your other terminal.
