Of course, it’s basically a communist idea from even before the Russian revolution.

To answer your question: since corporations aren’t allowed to own more than the buildings they work with, they could not buy foreign real estate - except for facilities or offices they really use.

I don’t think I know all the answers, it was just a interesting idea I read a while ago.

As far as I know it was never implemented, so weather it would work out or not is just speculation.
