To be clear, it's not the way WE chose to do it, it's how CORPORATIONS chose to do it, because it benefits them greatly: corporations can get all the rights that a human can get while being immune to most consequences such as imprisonment and the death penalty.
Corporations are neither agents nor beneficiaries. They don't take decisions. (That metaphorical abstraction is sometimes useful: here, it is not.) Some people are deciding to do things this way, and are benefiting from it, and those people are humans.
Corporations benefit from this, we humans don't.
