Yeah, this is definitely an interesting thought experiment (I assume it's that and not just a general gripe).
Smoking and certain drugs/alcohol, yeah I don't know if there is much there beyond people who depend on drugs for pain management, etc. that's kind of an aside though.
The interesting ones are gambling, gadgets and sex.
Gambling is something we all do every time we make a decision. Essentially, it is weighing possible outcomes with the risks and making a decision. Not gambling, in that sense, would essentially be living a pre-determined existence, without any ability to make unique decisions based on possible outcomes.
Gadgets could refer to absolutely any tool or invention. A gadget, is basically, any innovation. Like a fork, for example, or a car. These are all gadgets, in their own unique ways.
And yeah, the continuation of the human species has been touched on. Also....c'mon, lol.
