Yes, but you are traveling and working as a web developer. Try starting a family in a 160sq RV, and work from there at the same time. You will go insane and get a divorce after 8 months. (I totally made the number up).
I am not saying that people cannot do it, when I was little we lived in an apartment with very tiny two bedrooms and a kitchen (4 people). I was sleeping on bunk beds ...
Unless you are poor, are traveling in your RV, are an eco freak, or you're living in a densely populated area (China, Korea etc), there's just no reason for you to live in a tiny place.
This tiny house, however, would be great as a cabin where you can relax over the weekend, get away from city life.
