Someone has to own it and be responsible for it. Probably requires having a registered agent in some jurisdiction somewhere, for example.

Ying/yang corporations. Either corporation owns the entirety of the other.

I think Charles Stross(?) has featured this in books, with creations with bylaws that can be resolved as software instructions creating other corporations with bylaws resolved as software instructions, etc, with assorted corporations appointed as officers of others, creating tremendously deep layers of autonomous shell corporations.

Accelerando by Charles Stross is the book you're thinking of.

Thanks.
