Physical goods in a typical household
Those are some good starting points but I would refrain from using them as the end result. There are some fatal logical jumps in your example.

Moving house: A good one to use. If I were to guess, I think the ratio should have decreased due to tech. For example, we don't have those huge t.v. nowadays. No desktops for the most part. However, be careful about how wealth plays a role. Also, people moving into cities of California would be very different than of Colorado.

I think a better indicator would be the consumption category of GDP. Especially durable goods. You can find detailed numbers by year, state, category on the official website.

I hope that helps.
