Nearly every company does that. It's amazing how little many companies actually own. I've worked in offices where everything from building over furniture to even the plants was leased. The company ran with close to zero assets (services business). Pretty sure that this wouldn't make any sense if it wasn't for tax purposes.

Can be within the same taxing authority. I've facilitated facility transfers and leaseback agreements in the US.

Edit: Yes, you can't seize what isn't owned.
