> The rest of your post misunderstood a hypothetical I raised to compare and contrast with your argument, and I won't be addressing it
No, I didn’t misunderstand it. It was dumb at best, and incredibly insensitive at worst (I’m sure the gay community appreciates you appropriating their plight).
> When we talk about making drugs legal, we mean for recreational use. It's already the case that all drugs with a "demonstrated medical use" (let's ignore for a moment how that gets decided) are legal to use for medical purposes, and additionally, most of the laws have as a affirmative defense that your actions were medically necessary in some way.
My point is that we vary greatly in our legal attitudes towards those substances, even recreationally. Tobacco at 18, Alcohol at 21. Can’t advertise tobacco much, but beer commercials are literally everywhere. What are we going to do with cocaine? Heroin? Is there any difference in our stance towards those two?
> 2. The two legalized recreational drugs that we have (alcohol and tobacco) are sold in a variety of ways by jurisdiction, and our debate about removing the "only for medicine" requirement doesn't require that we resolve the debate about how we're going to realize that change in a uniform way. It's certainly not the most important question for if we legalize wider recreational drug use or not.
Well, ignoring that there are tons of other legal recreational drugs (caffeine comes to mind), there are actually some pretty general laws regarding them (e.g. tobacco at 18, alcohol at 21) and more specifically, advertising them. Implementation details of how we’re going to transition those drugs into the general populace is actually THE most important question in my mind.
> 3. "Maximum utility for society" is a notoriously hard way to make a decision, because we don't necessarily agree on what the metric is.
Horse shit. Deaths caused by drug warfare, death rates caused by complications (e.g. liver cirrhosis). Two metrics right there that nearly everyone cares about.
> Taking my hypothetical from before again - is it of maximum utility to prohibit gay marriage because it encourages straight couples to have more kids?
Your continued gay analogies are really just exposing your ignorance of homosexuality.
> It's generally better to start from first principles of the things an individual should and shouldn't be allowed to do on a whim, by getting permission from his peers, only with permission from a specific person the action is happening to, or never.
“by getting permission from his peers” is essentially what we do with alcohol and tobacco (hence the age restrictions, if we think of minors as individuals). “should be allowed to on a whim” is what we do for caffeine. They’re treated differently. What should we do for other drugs?
