You're willing to take significantly more risk that a routine drug prescription harms/kills you in order to streamline the process for drug companies? (Note that there already is a process in place for those with advanced diseases that justify a high-risk drug to take experimental drugs with knowledge of the risks).
Any realistic proposal (as in, we have an idea of how much extra risk we're incurring) is going to have a lot of technical details and probably require a huge amount of research to justify it -- it's human lives that we're talking about here. The potential $ savings are big but that doesn't matter if you're dead. Like I said way upthread, there is plenty of room for improvement, but "libertarian pixie dust will make everything better automatically" is the same thought process that led to collective farming and killing 10s of millions in Russia and China.
We need to do what we think is most likely to lead to the best outcome. There's a point beyond which that's no longer "more research", at which point researching more isn't taking it seriously. I have no particularly strong feelings about just where we are in that space - I'm busy saving the world along other lines.
For me that's not a non-starter. It's the start of a process that involves looking at just how much money gets saved (and by whom), just how much additional risk is borne by those taking the passed medications, and how much faster we're getting new (safe enough and effective enough) drugs on the market.
