It's the hippy ideal of compassion. The idea that by making life easy, and giving support that you can love someone into realizing the error of their ways and deciding to be a decent human being.
That shit doesn't work, it never worked which is probably why the hippies themselves were the ones to invent "tough love" (throwing your teenaged kids out of the house for the most minor of indiscretions) and the concept of enabling itself.
The solution for the problem is the middle road.
Being a junkie is not fun. It just isn't. They're tethered to doing a drug, they can't work, they don't feel proud of themselves, their lifestyle sucks, and their social circle becomes limited to junkies as they burn every person who ever loved them (especially their "enablers" because they know more than anyone what they're doing.)
The only real solution to it make it as unpleasant as possible to be a junkie and to make sure that even our lowest-wage workers have opportunity.
In other words, we crack down on users viciously but the only punishment is 10 hours in the pillory, without trial.
Sometimes we need to listen to the wisdom of our elders and the problem of addiction is one of those times. Bringing back the pillory would be effective.
