"Letting the market decide" requires you to actually have a market. If you have a market of manufacturers that all produce a product for around X, then it doesn't matter if I value the product at 100X or 1,000,000X. I'm still going to be paying around X + epsilon. That's the entire point of having a market. You only see people asking questions about "well, who captures the extra value? what's fair?" etc when you don't have a market. When you actually have a market, then these questions cease to be relevant, because the price is already set. The problem has nothing to do with free market concepts breaking down, or disagreements about what's fair. The problem is that we've artificially prevented this market from existing. Fix that and the problem goes away.
