I think we already laid out our argument too. A private company can do whatever they want with your data. They can sell it, exploit it, and block you from accessing it.
The government can do none of those things. They can't deplatform you. They can't exploit your data or sell it. They can't block you from it.
At least by design.
By design, having the government responsible for verifying your identity is far superior than having private companies do it, because by design they have to be truthful and forthcoming.
The flaw is that the system is failing and so right now the private system and government system are equally bad.
