i recommend you read Human Action by Ludwig von Mises (yes, you can download a good PDF of it and ebook for free from mises.org)

all marketable things are at base services

i can sell cars, or i can rent cars, but what the customer is paying for is transport, and thus public buses, and air transport are also delivering the same basic service

people like prestige items because they want to look like they are prestige, thus the plethora of stupid products with blings and prominent elite brand names that have turned into broad market items with low actual prices and declining prestige

you don't buy a house to own the house, you buy it to keep the rain and cold out, to stop people stealing your stuff, to store your food, to house your bed, which provides you a comfortable place to sleep

Tao Te Ching chapter 11:

11

We join spokes together in a wheel,

but it is the center hole

that makes the wagon move.

We shape clay into a pot,

but it is the emptiness inside

that holds whatever we want.

We hammer wood for a house,

but it is the inner space

that makes it livable.

We work with being,

but non-being is what we use.
