There’s a difference between choosing to trust the claims of someone who you believe has expertise that would be expensive or impossible for you to develop yourself, and having no option but to “trust” a certain party in order to perform certain actions. I think when most people talk about “trustlessness” in the context of decentralized systems they’re not saying you would never trust a surgeon, or a pilot, or a YouTuber who reviews smartphones, or an audit of a computer system.
