To me it just comes off as someone saying “that’s cool, but what’s the point if you aren’t making money? Seems like a waste of time.” It’s just very dismissive.

Like, if you grow tomatoes, nobody goes “damn you could sell these.” Because everyone understands that having a backyard garden is a hobby, with the benefit that you get some decent tomatoes, though at fairly high cost compared to just about any other source of tomatoes.
