You make a good point. Our relatively recently established history of NOT holding individuals responsible for the end results of their life-choices does make it difficult to change to a policy of “freedom with responsibility”.
By not holding up the responsibility side of the equation, we make freedom almost meaningless.
However, this does not mean that we should not work our society closer to “freedom with responsibility”.
You’re absolutely right. It’s a matter of timing. I can see defacto legalization because the government is too small to bother with it. The current path will lead to a crap hole.
