But if the network is entierely built upon selfish interest, you cant complain in the same breath that miner act selfish and steal your money because it's profitable to them, or miner empty block for the same raeson. Perfectly acceptable behavior then. Nothing more to expect from any conscious being.
That is exactly what I expect of a decentralized, trustless system: a web of greedy cheating bastards wanting to rip off one another so much that they can only come to the consensus of a working, fair system ; and in fact, of any form of society in general (which, at its most abstract level, IS a trustless, decentralized system, governed by the immutable and non-centralized laws of physics). I think any picturing of anything else but that is but delusion, with the purpose to misguide the preys at best, and based upon misunderstanding at worst.
If all the systems in the world that is designed by man is corrupted because of the greed that humankind has shown so far, what keeps bitcoin to be not corrupted in the end ?
Well that is why satoshi designed the bitcoin in a way that the personal profit could never be ahead of the general favor. What you are seeing with miners and forks and discussions is people who want more and more profits for themselves instead of other people which is exactly what bitcoin was created against.
You cant rely on human to be less greedy but you can rely on a system that is less greedy friendly.
