You're wildly optimistic to give these people even 15 years. The average person dies with 10 years of starting meth. Drugs are rampant, and probably one of the main draws for anarchists. It's no mistake that antifa's stronghold (the PNW) is probably the most drug-friendly spot in America.
I haven't been able to find a city budget for Portland this year, but I suspect dire financial straits. The city is being beat like a pinata at a rave for epileptic kickboxers, with a 1-2-3 punch of corona then riots now taxpayer flight. The city services that keep junkies fed and housed will be running low on money, and the police are resigning in droves. I can't see a wrecked city prioritizing safe injection sites over keeping the lights on. Of course, stupidity seems to run deep there, so maybe it'll be the last thing before Portland is consumed by the abyss. Either way, once the programs turning their suicide into a slow bleed fail, you'll see these people meltdown like never before.
