Yup, I agree. Getting PoB tuned exactly right is pretty much impossible and it gets harder the larger and more diverse the community gets. IMO a more evolutionary approach is the only way to solve the problem; lots of coins, launched by lots of communities, experimenting with many different implementations of PoB in conjunction with varied business models. The best implementations are the ones that survive. We can then use those implementations to inform the design of the base token, but since that token will be tasked with aligning the incentives of such a large and diverse community, it will almost invariably function sub-optimally, in which case it would make sense to minimize the impact it would have on the economics of the system by reducing its inflation rate to the lowest possible level.
