Earlier quoted context omitted.
My statement is not that people can't benefit from a PhD, but that it is not a strict requirement. You are presenting a strawman.
What is that strawman exactly? You are saying that anyone can do PhD level research with just a laptop and the internet. I am saying that that is extremely difficult and impossible for the vast majority of people.
The parent commenter seems to be suggesting that a PhD isn’t a requirement to work successfully on interesting research problems. It’s possible to go online and read the same papers everyone’s reading. You can still talk to people to get guidance and find out known things that are not published.
