Dopamine is a necessary neurotransmitter, there is nothing sinister about it. Even addiction is necessary , but we ascribe negative value to it when the repetitive behavior (not just any enjoyable behavior) becomes destructive to society.

So, it is largely left society to decide which addictions are "good" and bad, which generally politicizes the issue.
