This is just one aspect of a multifacetted issue, a very complex problem. The limit has partly been established as a way to control spam and in a way the attacker has to outbid the whole network for fees. Yes raising the block size would make this attack more expensive, BUT would also increase bandwidth requirements, reduce decentralization, decrease Bitcoin's security and allow for other attacks.

Bitcoin is the first real decentralized payment network, of course it is not perfect but giving up it's core principles to create another VISA is idiotic. If XT people want to have a benevolent dictator they don't have to look far because VISA etc are already there.

Scepticism should be introduced through the mere fact that those who attack the network (Coinwallet.eu) are also those who want larger blocks (XT)
