>That kind of napkin math is both dangerous and misleading. The block size limit is a security parameter, and the math above assumed that nobody was trying to attack the network. In attack situations, a larger block size is more expensive and more dangerous.
The costs under an attack scenario were not what the parent comment was making a claim about. The defence costs per transaction actually decrease with each marginal increase in the number of transactions, because the number of parties worldwide with the resources capable of attacking a blockchain diminishes as the cost of a successful attack increases.
>Also, the resource requirements for running a node are a lot higher than most people are willing to tolerate even at 1mb blocks.
Again, not relevant to the issue at hand, which is the cost of the computing resources used per transaction in a distributed network.
>The dynamic block size in ethereum is an easy attack vector that can be exploited by a large miner.

Ridiculous scaremongering.
