Hum.. so you prefer the USA Quantitative Easing approach maybe? Free money right?
WAT?
I don't like cabbage therefore I must like brussel sprouts?
Both of those approaches are artificial manipulation of the markets. The block size limit can be classified alongside them.
Seriously, again, basically I would not disagree to reassess when tx fee > block rewards.
Currently, excepting "stress tests", adding transactions to be blockchain have not seen any restrictions caused by the block size limit. If transactions increase to where the block size starts to actually be a constraint, that would be an effective change in operating conditions.
