Who has been lying to you? I can't believe you're capable of making the arguments you've presented and yet incapable of understanding why they're based on lies or at the most charitable, misinformation. I'll try to sum up where you have been so grossly misinformed rather than write a book worth of responses. Please feel free to break the arguments down one by one in separate posts and I'll do my best to respond if you like.
The value of bitcoin is as a medium of exchange, not as a medium of creating wealth. The whole point is to be able to have something that can be reliably exchanged like traditional money. The value of bitcoin has nothing to do with the ability to generate a bitcoin.
Let me say that again because it seems to be the most fundamental point that you've missed: Bitcoin has value because it is a medium of exchange, not because you can mine them.
If you think that bitcoins only have value because they can be created, you're missing the point. If you think that bitcoins only have value as an investment strategy, you're missing the point. It would be silly to say that dollars only have value because they can be minted. It would be silly to say that dollars only have value because you can invest in them. Dollars have value because they can be used to purchase stuff. Bitcoins have value because they can be used to purchase stuff.
Dollars would lose their value if people didn't trust them. They're only trustworthy because they can't be easily created. In fact dollars are easier to counterfeit than bitcoins. It is the scarcity (like dollars, only more so) and the convenience for exchange (like dollars, but more so in some instances) that makes bitcoin a valuable method of exchange.
Bitcoins have value because they are a scarce resource that is easily exchanged and are accepted as a way to temporarily store the value of your efforts in order to be exchanged for something you want. That's what money is.
The cost of electrictity is certainly present, but it's nothing compared to the cost of armored cars, banks, ATMs, driving deposits to the bank, law enforcement hours spent fighting counterfeiting and minting. Even the cost of managing the exchange of dollars when measured in electrictity is wasteful compared to doing the same with bitcoins. You seem very concerned about the way people are using resources on a planatery scale. Traditional physically produced currencies are tremendously wasteful. How can you be so against something that cuts down on the waste?
