It’s wasteful in the sense that you use more fuel to carry around more car. You have a harder time parking and maneuvering in a city, and you generally take up more space than needed. Most people forget that what they do has an impact but this does not remove the impact.

How many times per year would you say you need to move furniture? If you do it 1 day per month but carry around a full truck and the above mentioned disadvantages the other 30 maybe it’s not that bad of a trade off.
