I don't see why people are so freaked out by allowing the satoshi to reprice itself against real-world goods and services, if the security budget is X but a satoshi can't match it, mining has to scale to meet it, some will turn off that's the nature of the game. But we also don't know how much transaction fees added to the subsidy will be worth in purchasing power.
I just think you need to allow for creative destruction and let the market find its equilibrium without constantly having to jump in and fix a might be issue
