The System of Objects by Jean Baudrillard

As core of an Enter Fugue text as imaginably possible. A foundational text from the (absolute king and) French philosopher, it explores how modern consumer society uses mass-produced items not just for practical use, but as a system of signs and symbols that define human behavior, social status, and identity. 

He divides everyday things into three groups:

Functional: Modern items focused on practical tasks and technical efficiency.

Non-functional: Marginal things like antiques, driven by the personal psychology of collecting.

Metafunctional: Useless, bizarre, or hyper-modern gadgets that stretch the meaning of utility. 

So many more takeaways to be collected but this book will forever shift how you see the 'stuff' in the world.
