What I'm wondering is where is MisterBigg? He was the dude saying if we removed the blocksize limit then miners would be stuffing everything into one block, even things paying 1 satoshi. I think that idea has been thoroughly debunked, particularly recently - his school of thought cannot explain the current phenomenon, and we're nowhere near the 1MB limit. More evidence we should just get rid of it.
AFAIK I'm the one who pointed out that incentive first; MisterBigg either independently realized the same thing or was repeating me.
IIRC he gave completely different reasons that were proven wrong by Gavin's paper showing that including TXs is quite expensive due to orphan costs.
The orphan cost of including a TX for a standard 500byte TX is now a whopping $1,30
