This is an incredibly important point that I agree with. I would take this further to separate "legal person" from "mind", as I understand the mind is itself an emergent and self-supporting adaptive process[1], very common to find among any persistent complex systems. Politicians don't make politics, it's the other way around.
[1] I use this phrase to replace "intent", because outside of requiring the "intender" to be person who can be held to account with punishment or reward, the reward mechanism is the same environmental pressure.
