For sure, the first point is pretty critical to ensure market viability of a single payer system. The potential reductions in administrative overhead absorbs some of the expected reductions in reimbursement amounts that'd come with a single payer system. But even if you can make it work out from an economics standpoint, it can ultimately fail from a political standpoint if people feel like it's a failure. And there are a lot of entrenched interests that would benefit from a failed single payer experiment. My other points were geared towards that component. Letting the multi-payer environment die out organically leaves a grey area with potential consumer confusion and frustration during the transition period, and also leaves the infrastructure in place to easily roll back the single payer plan if you adequately exploit that frustration. Forcefully cutting over to a single payer system allows a clean break so both the consumer and provider side of the market has the opportunity to validate if the claims in the single vs. multi payer debate can be realized, without creating a giant attack surface for political and market shenanigans that could kill it before it really got going. It also raises the level of effort required to roll back the single payer system, since the infrastructure and and staffing to support it is reduced more rapidly than if taking a "let them die on their own" stance.
