Welp, I'm officially done trying to explain bitcoin to people, I'm officially on team "have fun staying poor"

I recently encountered one of the world's largest FUDders to ever exist. The global financial system had come up and somewhere down the line I mentioned bitcoin, this guy knows nothing about it so he asked me about it. I work with him daily so I know that he means well, but his brain just immediately went into FUD mode, he just immediately started looking for reasons why he shouldn't buy it. He ended up literally going down the list of each fud talking point.

What about quantum?

What if the internet goes down?

What if the government confiscates it?

What if someone just creates more bitcoin to ruin the scarcity?

What if someone just reprograms the blockchain to allow for more bitcoin to be created?

What if there's a secret backdoor to bitcoin?

What if the creator is secretly siphoning bitcoin from everyone to himself and the number you're seeing on the screen is just a fake number?

What if he put in the backdoor in a way that no one would be able to detect it? Since he wrote the code, he'd be able to do it.

I didn't have a good answer on the last few cos I had never encountered those specific questions since I had never come across someone so determined to stay poor, so I'm guessing that he took my not having an immediate good answer as him thinking that his suspicions were correct and so now he just perma-fudded himself and will never buy ????‍♀️
