Now do the gold mining industry, and then how USD is backed by armies. And then you can research Lightning Network on top of Bitcoin and how it can process an unlimited number of transactions.
1. The gold mining industry has nothing to do with bitcoin.
2. The gold mining industry has nothing to do with money.
3. The gold mining industry does not use anywhere near 0.1% of the entire energy production of the planet.
4. Just throwing the army in there for some reason, huh.
5. The lightning network does not "process an unlimited number of transactions".
6. The Lightning network does not scale.
7. Nobody knows how to make the Lightning network scale.
8. If the Lightning network worked, which it doesn't, it doesn't need to run on top of Bitcoin, so Bitcoin still does not need to burn 0.1% of the world's energy.
also the military/police/law/government defend you from being killed for your bitcoin.
That's an understatement. There are two restaurants within 100 miles of my home that accept BTC, let alone use LN.
If LN ever sees anything more than toy usage, it will fall over instantly, and become unusable.
