Plenty of people on the streets want all kinds of help. They don't want shit programs with a million hoops and strings attached, nor do they want gross dilapidated shelters also with hoops and strings plus predators prowling around looking to steal their shit (or worse) while they sleep.

Also, while the whole rock bottom trope probably holds some truth for many people, when you make every story all about it you kind of lose the plot. If you try hard enough, you can look at just about anyone's life who has recovered from addiction and create a narrative based on an upward trend after the "worst" moment or period of their addiction. If they had two periods that were basically exactly as bad, you dig around until you find some trivial reason to label the second period as worse, and thus the "real bottom." If someone had their worst period of addiction many years before they actually got to a place where they could maintain sobriety long term it was just a long journey for them. Etc.
