And why should they?
Did you miss the entire conversation here? The reason is to stop supporting the evil crime syndicates that are harming many many people. I have far more of a problem with that than drugs. I don't care if you use drugs. You talk about it naturally growing. Go for it. I personally don't care if you do.
But to act like there's no reason to not use drugs just because you could pick an apple off a tree.That is a huge oversight of the situation. If crime groups were illegally trafficking apples and killing people over it, you can sure as hell bet I would advise not to purchase any of their apples too.
We need an international effort to legalize personal production of all personally produceable drugs. Not public consumption, not a blanket for junkies, but just a way for people to use their freedom in NOT helping the cartels.
I'm not taking a stance in the "legalize it" debate. But I would point out that you already have a way to use your freedom to not help the cartels. You could choose not to purchase drugs. I'm not saying that it's necessarily reasonable to ask people that do drugs to stop because of the behind the scenes horrors, but to say they DON'T have that ability is untrue.
The one breakthrough we need to go even further than that, in my opinion, is effectively using hydrogen+hydrogen nuclear fusion as a fuel source. Then we could just establish our main base around Jupiter and stick a hose into the planet and voila, free fuel for everyone.
As cool as that sounds, if we start colonizing the solar system, chances are people are going to branch out if it's possible. People are going to find ways to live on as many planets as possible. I know that the technological barriers are much greater than that of, say, the Oregon trail, but presumably by the time we have colonized an environment as hostile as the moon or mars, we will be at least a little more nonchalant about space travel at the least. People will expand to the area available to them. People with differing viewpoints and conflicting aspirations will push for colonies elsewhere. Then they will all multiply. By the time we fill up the livable parts of the solar system, I fear we would have enough people using enough energy to have some level of impact on Jupiter. I don't know what exactly, but we should bear that in mind before we go raping planets for their energy. After all, we've seen how well it worked out for Earth.
Don't be silly. Mars is no place to raise a kid, and there's no one there to raise 'em if you did...
Now that you mention it, I've heard that it's cold as hell.
Of course you can't flap your arms and fly to the moon. After a while you'd run out of air to push against.
