"Fascinating! A little virus which will be unstoppable,
the supreme lifeform in all the universe,
destroying all other life until it alone remained!
Yes, I, Davros, would unleash such a force!"
As Am I. Everyone has a choice in the matter. What you are trying to do is invent some scenario that is so heinous as to beg for legislation and control and then, if I refuse to go along, you can go off on your name-calling "libertine" america-hater rants full of vapid propaganda gifs signifying no intelligence or reason.
That's no fun at all. People have choices. If they chose to take such a drug then they've made a poor choice and should suffer the consequences of their poor choices. That's the way that life is supposed to work.
And if you want a great example of this in action, look at areas where hunting has been banned and game animals are allowed to go uncontrolled where there are no natural predators.
You will find starvation, sickness, genetic mutations and stunted growth.
Go to a location where the population is hunted and the animals are healthy, vibrant and noticably larger in size than their unchecked counterparts.
Groups which are not required to suffer the normal consequences of life become extremely weak. That is what the nanny state creates: Weak, irresponsible people. That is why the constructors of socialist nanny-states love socialism. Weak, irresponsible people are extremely easy to control.
TV is a drug. It's dangerous. It creates stupid, uninformed citizens. If I could outlaw it I wouldn't. People need to suffer the consequences of their own mistakes.
Bears repeating a hundred thousand times
And who says they have no choices or do not suffer consequences? Jail is a consequence to evil behaviors just as much as starvation and disease are. We note that you compared the human race to a herd of wild animals, decying the fact that a compassionate society deems humans as having a greater value than that of deer or wild boar.
You compare the high-powered hunting rifle with the modern drug which culls the herd and makes it strong. Such a twisted mind you have. Your cruel words make you sound like a social-Darwinist Aryan Nation freak, or another Ebinezer Scrooge decying the "surplus population." Some "humanist" you are!
