Why buy Wagyu?

I'm curious, why would someone choose to invest in Wagyu beef? Is it simply because of its reputation for being a luxury product, or is there more to it? What sets Wagyu beef apart from other types of beef, and is the cost justified by the quality and taste? Additionally, is Wagyu beef a sustainable investment option, considering the resources required to raise and produce it? As an investor, what should I consider before making a decision to invest in Wagyu beef?
