How much energy, resources, etc are required to sustain cash and credit card transactions? Think of all those banks, skyscrapers, ATMs, computers, money printing machines. All of those things exist to power the security of the modern financial industry. If bitcoin powers the post-modern financial industry, the resource savings will be enormous.

And yet the actual functionality of Bitcoin - a simple ledger - could be implemented using much less resources than are used to maintain the Bitcoin network. It's curious, isn't it?

  Isn't it the double-spending solution that requires all those resources, not the simple ledger?

  The whole point is decentralisation and the absence of a regulator. That's what cannot really be made "cheaply" without very serious compromise.

Why do you think banks, skyscrapers, ATMs, computers and money printing machines will go away just because of bitcoin? They will all still be there, there will just also be lots of machines calculating SHA256 hashes
