No, of course not. I eat at restaurants all the time. People will be hungry again shortly, even if fed wonderfully well. There are other things to worry about more, like if they are meeting food safety codes, which some don't.
I did therapy with a military chaplain. I had a really positive experience there. He wasn't being paid by me to deal with me. He was on salary. If I got better, that had no bearing on how much he made.
Some of the best hospitals in the US put their doctors on salary a long time ago. How many tests they order has no bearing on their income the way it can for a lot of private practice.
I have serious health issues and have gotten healthier via alternative approaches. I've thought a lot about what's wrong with modern medicine and I do think the way it gets paid for in the US is part of the problem. That doesn't mean I would never go to a doctor.
I've had lots of medical care and I would have died without it a long time ago, but I also was told at some point "People like you don't get well." When I didn't like that answer, I was scheduled fewer appointments and the rest of the world has since decided to malign me as a nutcase who "refuses" to see a doctor, which isn't the case.
I'm not an anti-intellectual by any stretch of the imagination. Nor do I think you should never seek expert advice. I'm just saying that advice free from conflict of interest is actually very valuable and one of the things offered by things like advice columns.
Example scenario:
If you are crying on the shoulder of some woman friend about your marital problems, you ultimately get divorced and end up with her, you have to wonder if she was really giving you advice designed to enhance your life or designed to enhance hers. You have to wonder if you can really trust her. It's a situation where she probably should have recused herself and told you "I'm not the person to get advice from on this matter. Sorry." But that's often not how it goes.
