You have enlisted a good number of topics here, I already knew about the endthefud and read some of the threads there already but the last one from Vijay is quite new for me, and it's really a deep one. The author of the post really made a good effort to compile this up. Overall, the conclusion is enough to understand what the Vijay is talking about, which most of us already know that BTC is the new currency how it will dominate all other types of currencies.

That's why BTC will be adopted more and when more people will use it, due to scarcity factor it will increase in value thus proved to be a good source to store the value of money in it. Speaking of mining, there are some constraints like block size which can be managed to some extent via lighting network and the transaction fee which can also be managed to some extent via lighting network speaking of energy, I can say for sure that after reading the endthe fud website's article OP will know most of the concerns related to BTC mining energy are just excuses to start another side business of green energy. You will see a lot on this narrative.
