Alcohol.
Lots and lots of people lean heavily on it and think that alcohol is the spice of their life. When, it contributes to so many problems than it’s so-called benefits. We tried, in America anyways, to outright ban alcohol. Problem was that the person who wanted it banned, was too extremist.
Like he didn’t think it all through and think just going for the jugular of the problem is what will work. When, it didn’t and just made people work around it until eventually the ban was dismantled.
So, since then, we’ve been putting up with drunk drivers, drunk disputes, drunk abusers and other issues. I still wish we could just slam our hands down at the desk and demand we sit to discuss in how to properly deal with this issue than people proclaiming that it’s not a problem.
As destructive technologies advance, any level of crime will become unacceptable, because eventually it will take only one person to create (for example) a bio-weapon to kill 10% of planet population. I predict we will have to design every new baby to fit into society, and ban humans with destructive impulses from being raised on Earth. Mandatory eugenics for the whole planet. Reserved free-range fuck-around planets for dangerous organic humans. Blowing up a Mars dome hurts only a few, because connecting tubes have air locks, and viruses can’t survive outside. “Blast your prehistoric frustrations away in our all-out war park!” -God of War Inc., Mars.
