Nobody has a switch to just turn off all power in the Philippines either. That wasn't the point. The point is that it's a massive energy waste that grew the same exact way a cancer does--out of virtually nowhere and uncontrollably. If it never would've existed, that's a huge amount of waste that simply wouldn't exist either.

Bitcoin is anything but efficient. It takes massive amounts of energy to make a simple transaction. Far more than any current currency transfer network. If it continues to grow, and if it would horrifically become mainstream, energy usage would be several magnitudes higher than it is now.

Right now its primary uses are for bringing more people into the scheme to eventually dump for cash, and to exchange for illicit materials online. It's a very niche case used by a tiny, tiny fraction of the total population, and it already consumes more energy than many entire countries. Extrapolate that energy usage to 1000x the current population and 1000x the current usage to assume everyone is in on it and using it regularly for normal transactions--at a minimum, we're hitting 1000x energy usage rates.

That's energy usage exceeding China and America's total energy usage combined. Just to send bits on a network. You'd be more efficient carting blocks of gold manually across the world for every transaction.
