I think Bitcoin's one use case as a banking system to take over a $20 trillion+ banking system is far more than enough. The average person isn't going to care about "my money can also be used natively to pay for slow cloud computing services". They just want the most secure banking/payments system, which is Bitcoin.
Banking system doesn't need bitcoin any more than it needs cancer. The banks handle fiat, why in the world would they support something that's openly anti-bank & anti-fiat?
What are you thinking?
Eh? Because if it becomes as popular as most people here would love it to become, it will destroy their evil fucked up financial system they've created and used to enslave us for decades now and with the damage the banks have done in the past decade especially I hope to see that happen, maybe within the course of a revolution, but hey even better.
