imagine this: someone asks a question, the answer is usually too complicated to give "verified answer", like some people need better security or someone needs more privacy. On top of this there could be multiple solutions to one problem. You can't "verify" everything i say online, no matter the topic.

If it's too complicated to give a justifiable explanation on a concrete topic, you don't fully understand what you're talking about. There may not be one single correct answer, and how to balance privacy and security is a subjective topic, but claims about privacy and security should be verifiable.
