That's not a counter, it's more selection bias. Nature is a good place for mushrooms to grow, but that doesn't mean it's easy to grow them yourself. Cannabis is a very successful plant but it still isn't as easy to grow in your home. You can go outside and find a fern almost anywhere in the world- they're one of the oldest, most successful, and most widespread plants, but they are a pain in the ass to grow yourself: http://articles.latimes.com/1991-10-27/realestate/re-649_1_m...
Sorry, I may have been too vague. I grew them in a large plastic bin in my bathtub. I got the spores and was able to start the mycelium without any bacteria problems, somehow (My kitchen was no more sanitary than you would expect from a 21 year old bachelor). I really had no idea what I was doing so, based on the stories I hear of other people trying and failing several times before giving up, I assume I was just exceptionally lucky. :)
Edit: Ah, I get your point about selection bias now. Yes, based on self-reporting on drug forums I am surely in a small minority of clueless yet successful psychedelic mushroom farmers. I suppose if I ran through a minefield once and didn't lose any limbs, I would think that was easy too: "just run in a straight line as fast as you can, no problem!"
I also had success growing mushrooms at around that age.
I just followed the instructions and did try to take extra care with cleanliness, my guess is that as we're both here on HN we're probably predisposed to be better at following a process.
