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.
