If an AGI can outclass a human when it comes to economic forecasting, deciding where to invest, and managing a labor force (human or machine), I think it would be smart enough to employ a human front to act as an interface to the legal system. Put another way, could the human tail in such a relationship wag the machine dog? Which party is more replaceable?
I guess this could be a facet of whether you see economic advantage as a legal conceit or a difference in productivity/capability.
This reminds me of a character in Cyberpunk 2077 (which overall i find to have a rather naive outlook on the whole "cyberpunk" thing but i attribute it to being based on a tabletop RPG from the 80s) who is an AGI that has its own business of a fleet of self-driving Taxis. It is supposedly illegal (in-universe) but it remains in business by a combination of staying (relatively) low profile, providing high quality service to VIPs and paying bribes :-P.
