From the start the most frequent real world use cases were buying drugs and illegal services online (silkroad), and eventually other cases like ransomware (cryptolocker, wannacry), and a few other marginalized cases.
So in my view the mainstream adoption and glorification of Bitcoin is a tragedy, that I do think Satoshi himself (or Hal Finney) would eventually disagree with. The result of it is a colossal amount of wasted energy that could be prevented with traditional technologies (banks, public records, government databases), or more efficient alternatives (proof of stake, other forms of consensus) and hopefully more transparent as well.
I don't think it is necessarily going to play out that way. While I can't think of a single use case that Bitcoin fulfills that the alternatives don't, digital currency, of some kind, is inevitably going to play an increasing role in our lives.
What is now known as "cryptocurrency" (blockchain based tokens) are just one kind of digital currency. There are at least 2 other kinds I can think of:
- Centralized databases of fiat-exchangeable equivalents (A "Fedcoin", Amazon vouchers etc)
- Federated Chaumian/Brandian anonymous digital cash systems (the forgotten cryptocurrency).
Personally I think it's only a matter of time before we get a digital currency based on one of these models sponsored by central banks / governments.
I just think it is a matter of time before someone hits the right social cords with the right crypto and the wind is sucked out of BTC overnight. There are certainly tons of people trying.
Bitcoin consumes 'more electricity than Argentina'
Also the equipment used to mine cryptocurrencies doesn't magically appear. What percentage of the world's mining operations for copper, lithium, silver, etc. goes to building crypto-mining rigs? How does that total output compare to the 3k tons of gold?

I don't know how much of that $75B/year translates to CO2 emissions, etc, or how it compares to BTC or what have you, but you can buy a lot of externalities for $75B.
I'd put my estimate at something like 30-150 megatons of CO2/year for gold, just because I'd be surprised if they spent less than 10% of the cost of mining gold on fuel, or more than 50%. So I'd be neither surprised if gold generated less CO2 / year than Bitcoin, or if it generated like 4x more.
Bitcoin is a ten year old project, written in mutable code, that's invisible, intangible, and essentially replicable by any number of competing crypto projects or forks. It may be useful, or it may not be. It may stick around, or it may disappear. Either way, it's not seriously comparable to gold.
The same cannot be said for BTC.
