because some substances/ items actually cause harm and have no fucking reason to be in civil society
That can become a convenient excuse to justify forcing your personal preferences on other people. And if "civil society" reaches beneath my skin to claim ownership on my very body itself, it's hard to avoid thinking it as pretty totalitarian.
the concept of freedom?
completely untouched by this simple truth
That is an absurd claim. Of course freedom is affected by regulations. The question is whether a given set of regulations achieves goals worthy of the sacrifices it requires. Which, I suppose, is easy to answer if you, personally, aren't being called to sacrifice any activity you'd like to partake in.
we, society, LIKE restrictions on, for example, kiddie porn.
Yes, we do. We, as a society, are addicted to power and enjoy wielding it. That does not make such lording over others right. If anything, this particular addiction has caused more misery than all others combined.
this is where you get really mad at me and compare me to an authoritarian freedom crushing "statist" goon... just because i don't want people freely trading in kiddie porn or heroin. which would make you a brainless teenaged drama queen. let's hope you're not
Your entire argument is just one long appeal to authority, mixed with think of the children and with a little bit of an argument from intimidation at the end. You are an authoritarian, or if you prefer, a power addict.
As for trading "kiddie porn or heroin", these are very different and quite obviously so. Heroin is a chemical substance the production or use of which does not imply harm to anyone or anything except the user. A society might seek to ban it on those grounds, but current one jails addicts so its hard to take seriously it's concern over them. And that doesn't really leave many reasons other than a power trip.
