Assuming you do it correctly, you should be able to twiddle the brain's reward systems so as to produce sensations more pleasurable and fulfilling than any lesser stimulus.
That sounds like one of the myriad benefits, to me...
Depends on your definition of "correctly". Based on the rest of your comment then perhaps the Olds' experiments with rats would be ideal:
In 1954, James Olds and Peter Milner discovered that a rat would press a bar to receive a brief impulse of electricity through an electrode implanted in certain areas of the brain. Although it was known that such stimulation in other areas of the brain could produce motivated behaviors of eating, drinking, sexual behavior, or aggression (and that lesions of the brain could produce the converse behaviors), it now appeared that psychologists had discovered a "brain reward" system. The ESB was serving as a reinforcer. Rats bar pressed at rapid rates for 15 to 20 hours until exhausted in order to receive the stimulation. During the process, they ignored food or water, and rat mothers ignored their pups.
I'm libertarian, so I believe it would be your right to choose to pay to implant something like this if you were to make a fully informed, mentally competent decision to do so.
However, I wouldn't want this: every other addiction has some form of intrinsic rate-limiting effect; be it passing out/hangovers for alcohol, male refractory periods for sex, dopamine receptor changes for cocaine, etc, etc. The "correct" implementation of something like this would have no such impediment to instant, ultimate junkie status.
