I want to self-host my account credentials. Or more accurately, I absolutely do not want Apple | Google | Microsoft to be able to lock my account, and thereby lock me out of every other account. Especially as two of them have already done so.

If I could act as a passkey provider for myself, similar to how I can do that with SSH, then that’d be great. I do not comprehend why it’s not allowed, apart from being part of a further grasp for power by those companies.

Well, you can store your passkeys in a password manager like KeePassXC. Open-source password/passkey manager actually means more or less self-hosting your credentials as a third-party provider.
