Given that fact, would it not be most beneficial to focus not so much on the potential for corruption but the greater good of humanity?
Don't give them any more bright ideas..........
Actually no they cant. It's illegal for them to do so because Society recognizes that it's highly detrimental to people to a FAR worse degree than alcohol. (which is also illegal for children to consume)
Why not prohibit alcohol again?
Because it's not nearly as dangerous as heroin and can be (and is) enjoyed by billions of people all over the world in moderation without their becoming addicted and ruining their lives. As with anything, there are those who seem unable to use it in moderation but our society has made a choice that is it willing to accept the level of mayhem that alcohol produces. Some cultures have made different decisions.
Why not prohibit tobacco (some do favor it)
Why not make private ownership of motor vehicles, firearms and blades, swimming pools, mop buckets etc. illegal?
Why not ban gangsta rap, sexually oriented advertising and fast food?
Why not ban the sale of clothing that might lead to some kid being shot for his shoes or jacket?
Of course not, same rationale as above.
It would all be for “the greater good of humanity”.
I fear that my post has been misinterpreted, possibly because I failed to state my position clearly enough. I am, of course, not advocating the wholesale and mindless illegalization of anything that could be conceivably detrimental as you seem to infer, only a reasoned and balanced approach to lawmaking. Again, given the fact that human beings are, by nature flawed and therefore there is always potential for abuse and corruption anytime a profit is to be made, would this be a valid rationale for dispensing with a system of laws altogether, merely because there is a potential for corruption? Prohibition was repealed because it was a wildly unpopular law and it created far more problems than it solved. It did not, as it's proponents had suggested at the outset, address the greater good of humanity.
