Why is every researcher treating addiction like it's bad behavior that needs to be avoided in order to be cured, instead of researching ways for humans to keep on getting the satisfaction, while curing the side effects?
(I know "curing the side effects" sounds bad, but it's basically what we want).
It may not be possible. Addiction is a disease of our systems governing attention and motivation: Normally those systems should adapt so that we pay attention to those things which are most relevant to our long-term well-being, and so we are motivated to act in ways which sustain our well-being and success.
Addiction occurs when a pattern of exposure to an acute stimulus activates our reward system in such a way that our attentional and motivational systems are subverted to cause us to seek out more of that short term reward, at the expense of our long-term happiness.
The "satisfaction", as you put it, is the subjective experience of that overwhelming, system-breaking reward signal. To get that experience without the resulting behavioral consequences would require us to fundamentally augment how reward affects the brain. It's doubtful it's possible to do that with addictive stimuli without causing wide-reaching effects on general learning and adaptation.
Sounds like a "happy pill" compared to which any other reward mechanisms pale in comparison. Or, in the opposite direction, a "sad pill" compared to which no reward mechanisms can work.
