That's a very simplistic view of how it works in even a medium sized real company. Google SSO is already available for many external services you might use which is a lot easier to integrate than doing and maintaining something yourself. Especially because if there's an issue it's blocking everyone in the company at the same time. It makes sense to outsource that if it's not your core business.

I am talking specifically for the case of OP: a big company with 10k users that already has AD.

You are arguing a strawman.
