Yes, don't trust anyone, it will only lead you astray.
When you said about satoshi being a group or a person, I was reminded of the movie BIG MOUTH which is a crime fiction drama movie that tells the story of Bigh Mouth as a ruler who can do anything, and it is not known whether he is a group or a person.
But at the end of the story Big Mouth is an anti-government group and has many members.
https://www.imdb.com/title/tt21195490/I have actually watched that drama. It has a lot of suspense and a great storytelling. That also reminds me, The person that we are all looking for could be right beside us and we won't even know. I have speculated many times that the original boss of the big mouth group was someone else. Turns out, it's someone that you will never expect to be. I really enjoyed that drama to be honest.
Drama and entertainment aside, even if they are lurking around us that doesn't mean we need to dig out the truth. Bitcoin is better off without the truth and it is doing a great job being what it is meant to be. So let's just forget all that and focus on Bitcoin. when you are thirsty, you drink water. But you never think of who created it. And that's how Bitcoin is. Take the advantage as long as you can and don't think about who created it.
