No, I do think he's right. They might be honestly curious about the details of living on a boat, but in the end not really that interested in pursuing it for themselves. Many think of it as something they might really like to try out for a year or two... tops. others, likely see the appeal but realize that it's not a realistic option for them (spouses, children, pets, etc.). If everyone wanted to live on a boat too, there is no way your costs would stay the same (slip costs would go through the roof).
