The same way that coffee runs the gamut between the gnarliest of instant coffees to 3rd wave single-origin craft brews. Almost every step of the production chain is different, and while they're all technically coffee, they're basically different products, that get enjoyed in different contexts. Weirdly, I enjoy a 80s style black coffee when I'm at the greasy spoon around the corner - it just feels right.
Your Green Tube Mystery Powder is a product sold under a name that is probably technically correct (Parmesan) but the "real thing" is a product that behaves completely differently and doesn't meet your wants or needs.
