I see many scenarios where the items would add up to less than this. I see more where it doesn't. e.g.: What you say makes sense for a single person who owns a PC, a TV, and Ikea + amazon furniture.
Now imagine a couple or family, who's been (criticize the capitalist/consumer culture or not) buying nice wood furniture, has a well-stocked kitchen, multiple computers, hobby equipment etc.
I encourage you to run a rough estimate of your own household's items. Do the same for your a neighbor's; a friend's.
And yet when you die, the contents of your house (for inheritance purposes) will most likely be valued at under $10K and nobody will raise an eyebrow at that.
My nice wood furniture has had three owners and is almost 70 years old, so I certainly think it’s possible to own nice things and not be a wasteful consumerist.
