Some people want to gamble and the gambling industry provides what they want.
How would you like it if people who didn't care about your hobby started questioning the social benefit of allowing you to do it?
Maybe I enjoy having an arsenal of late-model machine guns, doing research on rare nuclear isotopes, brewing cholera in my septic tank, tending a Japanese knotwood garden, raising lantern flies, and breeding new strains of cold viruses.
Perhaps society should continue to restrain such hobbies.

In this hypothetical scenario, is my hobby actively harmful to society?
Some people would enjoy killing people but we don’t let them do that.
