Most of these comparisons sounded pretty identical to the ones from the "If I had the intention to lobby for a ban of Bitcoin mining, I would use references like the one below" list to me.
Earlier quoted context omitted.
You don't need banks to store cash. Bitcoin without electricity is useless, cash on the other hand is not.
But you do need banks to store cash. And the bank better have a secure vault and security guards and cameras and all that. An elliptic curve key, which is what possession of bitcoin is, is just a large number. To send a bitcoin you need to create a "transaction", and in fact the only aspect of generating a bitcoin transaction that requires energy is the SHA calculation, not something you can do in pencil, the EC math…
So people mine bitcoin, which is really just validating the transactions on the network, and they get paid in bitcoin for doing so. However, they will receive fewer and fewer bitcoin over time because of the fixed supply. At some point doesn't mining become unprofitable, causing the network to crash. And if the price drops doesn't this exacerbate this problem? Would love some clarity here.
Can someone explain something to me: So people mine bitcoin, which is really just validating the transactions on the network, and they get paid in bitcoin for doing so.

Is this not the price paid for the trust, security, and utility that bitcoin brings? I don’t hear alternatives being suggested.
How about not bitcoin, where a transaction doesn't consume 9 day's worth of an average family's energy budget? Utility: a transaction costs $10, right? It's useless. Security: Have you followed this? The actual recommendation is to print your private keys and stick them in a vault. Trust: It's funny that, fundamentally, people started doubting the Federal Reserve when the gold standard was abolished, because suddenly…
"Also, one can argue that Bitcoin actually saves energy. The world’s financial system requires many resources beyond the electricity to run servers." What a bunch of crap. Bitcoin also needs servers (i.e exchanges, uses computers, routers, switches etc. )
Bitcoin's electricity consumption is unfortunate, it's difficult to assess whether it is a waste or not. The current position blockchain tech can be compared to the state of networked computers in the 70s and early 80s. Not a huge amount of value delivered at the time, yet very few could have foreseen the impact of the internet and personal computing on the world. If blockchains and distributed computing does present…
Yes.
One of the big selling points of Bitcoin is that it's meant to be decentralised but it doesn't look like this plays out. Proof of work seems to inevitably lead to all the power going to parties that can afford specialised hardware who are in countries with low electricity costs. Running a Bitcoin miner on commodity hardware now is pointless which seems to go against the spirit of Bitcoin when it started. Was this pre…
At inception? No. But Satoshi was made aware of this problem. Here's a long passage from Nathaniel Popper's Digital Gold:
Laszlo’s CPU had been winning, at most, one block of 50 Bitcoins each day, of the approximately 140 blocks that were released daily. Once Laszlo got his GPU card hooked in he began winning one or two blocks an hour, and occasionally more. On May 17 he won twenty-eight blocks; these wins gave him fourteen hundred new coins that day.
Satoshi knew someone would eventually spot this opportunity as Bitcoin became more successful and was not surprised when Laszlo e-mailed him about his project. But in responding to Laszlo, Satoshi was clearly torn. If one person was taking all the coins, there would be less of an incentive for new people to join in.
“I don’t mean to sound like a socialist,” Satoshi wrote back. “I don’t care if wealth is concentrated, but for now, we get more growth by giving that money to 100% of the people than giving it to 20%.”
As a result, Satoshi asked Laszlo to go easy with the “highpowered hashing,” the term coined to refer to the process of plugging an input into a hash function and seeing what it spit out.
But Satoshi also recognized that having more computing power on the network made the network stronger as long as the people with the power, like Laszlo, wanted to see Bitcoin succeed.

That highly depends on the hashing algorithm used. For Bitcoin this is SHA256, which is very well-suited for ASIC implementation. The algorithm of Ethereum was deliberately designed to be ASIC-resistant, but GPU-friendly, therefore GPUs (which are kind of a commodity) are the hardware of choice for Ethereum mining. Monero takes this one step further by having an algorithm that is ASIC-resistant and that can be mined…
Frankly, it will be interesting to see Monero's distribution. Because I was there when a glut of Cryptonight coins were announced. The selling point was CPU mining was back.
Quite a lot of people abused the AWS free credits to get a leg up and mine tons of coins.
But the most interesting was the guy who worked on a CUDA implementation to the Monero's mining algorithm ie a GPU miner. For a long, long time this mining software remained private. I believe it was only after the BTC crash to 300 and hence, Monero's to lower $1 levels that this got released publicly.
