I think the best approach is to just clarify what he's saying. So you're going to miss out on the greatest wealth distribution in modern history because you think the CIA invented it? This is what you'll tell your grandkids when they ask you why you didn't buy bitcoin at 58k?
Regardless of who Satoshi Nakimoto was he's not around & no single person or organisation controls Bitcoin.
Bitcoin core, the most widely used validation software is the most scrutinised peice of software in existence. Regardless of who is mining the blocks, every block is validated by that FOSS software.
I believe it was the NSA that invented SHA & Bitcoin uses SHA256. I don't recall the CIA being involved but I guarantee they use it.
It's like saying I'm not going to use Tor or torrents because I don't know who invented it.
