Again. Whats your problem of half full blocks? We both know most of the incentives for different entities in Bitcoin and it works beautifully. Also spam produces negligible fees. But my questio is about the blocksize.

Insufficiently full blocks leave no incentive to pay fees. Which leads to near zero fees. Which knocks hashrate offline. Knock down enough and you can expect reorgs and double spends. The subsidy protects us from this for the next century and change. After that we have to see where this goes.
