You said yourself that a lot of money would have= been lost if the two hard forks cited weren't resolved - that's th= e correct incentives at work again.

I will assert that the block size = is political because it affects nearly all users to some degree and not all= those users are technically inclined or care to keep decentralisation in t= he current configuration as you do. This debate has forgotten the current a= nd future users of Bitcoin. Most of them think the hit to node count in the= short term preferable to making it expensive and competitive to transact.<= /div>

We all= need a little faith that the system will reorganise and readjust after the= move to big blocks in a way that still has a reasonable degree of decentra= lisation and trustlessness. The incentives of Bitcoin remain, so everyone&#= 39;s decentralised decision throughout the system, from miners, merchants a= nd users, will continue to act according to those incentives.
