When single payer creates a cookie cutter 'coverage' list... what happens when an item someone wants covered... ISN'T?
It does nothing to change the situation. Unless you go to the 'everything is covered for everyone and we will stick future generations with the bill' plan.
Everyone gets a basic coverage plan and if you want a supplemental plan to cover things the basic plan doesn't cover, you can buy one. It's not really that hard.
