It reminds me of that video we all watched a while ago about the $10,000 crystal healing bed 
I tend to agree with that part you quoted because a lot of people get caught up in needing “natural” remedies and what’s more natural than a rock?!! This then creates the problem of Spiritual Bypass where people will brush their problems under the rug of spirituality and claim they’re fine, REALLY!
I don’t think believe in crystal healing or crystal magick is bad in general. I’m an animist and know that each crystal, rock, stone, etc. has potential for Spirit. It’s when people start to dismiss science that it becomes a large issue.
