No, that bit is an opinion. Don't forget most of us are on this forum because we have an interest in canals and boats so the thought of a boat being your only home might seem attractive.
Now I'm going to sound like a stuck record but how many people do you think could live on a boat?
I know some people who wouldn't step one foot in a boat due to it's unstable nature and fear of water. Space is very limited. Security fears. Lack of convenient utilites (filling up with water, generation of electicity, emptying toilet, no WiFi, etc).
On top of that, those who want to make a financial future for themselves could never see a boat aa being as good investment as bricks and mortar.
