I'm not trying to argue but genuinely curious what you think that conveys because I have seen this point or a variation brought up multiple times by different people and it always goes over my head
I think it's an interesting philosophical question, like how it's presented in Sapiens [1].
But concretely what I mainly mean is, if a company "fails" (and while there's lots of different definitions of failing, let's here take the most extreme one, where the company runs out of money and just has to fold) then it's not like a person is dying. Debt will be restructured, employees can be laid off, it can be bought/assets sold off, and most notably the actual people who profit most off these companies are substantially protected since the incorporation protects their personal assets from liability. Their biggest threat is the loss of stock price they presumably own, and that's a risk profile they've very clearly accepted. So when a company "dies", it's typically not really death in nearly the same sense that we normally think of the word. And it's slow, with (typically) no one person being a big load-bearing point, and tons of options and exit strategies and protections for people's personal affairs.
This resiliency, flexibility, and non-corporealness means companies almost always have more power in negotiations.
Compared to a human of mortal flesh, who typically have somewhere between 0 and a few months of runway before cobra payments and lack of income start to strain spousal relationships, mortgage payments come in danger, etc. And the 1-2 breadwinners, either of whose income loss is an existential risk to the family, are single points of failure if you're laid off or fired. Are typically scrambling to lock in employment again.
I think that makes sense. Because they are incorporeal, they have fewer and different needs to fulfil, and this can give them a bargaining advantage.
If this is what most people are trying to say, I think the incorporeal language is much more direct and clear than calling them fictitious, which has other meanings
