OK. I can accept that. In the theoretical sense I think that basic libertarian principles are extremely obvious, and it's strange to me that people refuse them out of hand. Of course I know that in practice you also have to weigh the potential negative effects, and sometimes that does outweigh the value of giving people freedom of choice, and sometimes it doesn't. This seems to be the criteria that should be used when deciding if to ban things like this.

As such, I do agree with what you are saying. In particular, your point about why people don't in practice weigh the possibilities in this way seems sadly accurate.
