In my opinion I think a lot of it comes down to comfort. Sitting in your home and reading about other people's successes and failures. The reason I say this is because just last year I made the decision to buy my first SFH at the age of 23 and I didn't know much about real estate and definitely didn't know of BP. So I didn't have all the resources I do today I just went out and got an agent and start looking for houses and went with my gut and bought a turnkey SFH that I rented out 2 weeks after closing and brings me a profit of $500 a month after expenses. Even when everyone was telling me not to do it.
After learning about biggerpockets I started reading a lot and I noticed the more I read the harder it was for me to take the next step. I had a clear plan of what my next step would be but I got caught up in the threads of what's right and what's wrong. I'm not saying educating yourself is bad and sure you can say I probably got lucky with my first property but I'm glad I did it because it worked out great and I think I just need to go back to my plan and execute it
So in my opinion I think people get scared on here thinking that their way is wrong. And you gotta follow the most successful investors to get it right otherwise you will fail. There is more than one right way you just gotta get out there and do what you believe is the right way for your situation
