There are some people who can’t just smoke weed. They need highly complex concentrates that require specialized gear to vape/smoke this stuff that is vastly stronger than what most users would want.

In booze terms the comparison would be between the guy who is fine with a vodka on the rocks vs a guy who needs to create a still that releases the grain alcohol into an ice luge to make their drink which is 2x as strong as the first guy by volume.
