Utilitarianism: Get ASIC mining device to as much people as possible, so that a 51% attack will not be possible
Nah, the rational egoist is more creative than this. He is an entrepreneur not an idiot. There are many ways to profit by disrupting markets. You don't get rich by sitting on your ass and thinking like everyone else.
Suppose our egoist is pirate for example. Collect 400k BTC debt, convert to USD, 51% attack, payoff debt after BTC devaluation, go off on your way with a suitcase full of cash, and without breaking any laws.
Worst case scenario btc holds its value and you just pull a regular pirate. Everyone seems to be convinced that a 51% attack is the death of bitcoin though. So you should be safe from breaking the law.
Seems like a legit business plan.
[Can't wait to see someone pull this off! This is what is called 'creative destruction'.]
