If all shopping centres and brands disappeared, retail would still exist because retail is what remains after eliminating those layers.

This is what happens when people awaken their desires, they become a type of consumer, responding to a need to socialise with other through the purchase of products, where the physical product, the service provided nor what is seen is the most important thing, but the intangible.

Retail is people responding to the social need to subsist and evolve thanks to the adaptation to the ever-changing environment.
