I think there may be some bias to your information sources. For example, I have a friend who was long time single and one day he told me that marriage is awful, nobody likes it. Well, turns out that none of his friends were married so all his information was discussion in the break room at work, of course people are much more likely to complain about their spouse then suddenly profess their continued domestic harmony. When was the last time someone shared over r lunch how they didn't argue about something? In this case people are more likely to talk about an activity if they are interested in the money angle.

I have hobbies with and without money. I never talk about the ones with no profit aspect. I just spend time enjoying them. I like woodworking, cycling, and making things around the house.

I do talk about my tea shop. It is a hobby business and I love it. I run it as a fairly serious business, and it makes a decent amount of money, but I don't optimize for profit. Eg, if someone is unhappy they get their money back regardless. I optimize for fun and happiness.
