I would prefer for crypto to be gone. Based on my understanding of blockchain, I don’t see how it can be used as currency ever. Blockchains can be extremely useful, just not as currency.

Hm, my understanding was that blockchain was the technology that handles the distributed ledger rather than the currency itself. Blockchain seems useful to a point in this realm, but is, like we both know, extremely energy inefficient and unsustainable.

The only thing you can really do about stolen tokens is have some authority de-list them and re-issue new token to the victim. That’s hardly a solution. It also extremely centralizes control, which runs antithetical to the purported benefits of crypto.

No arguments here. Though I think there could be better solutions out aside from using some centralized authority to delist stolen tokens. Blacklisting certain wallet IDs could be a crowd-sourced project, much like how blocklists for adblockers are largely community-driven.

Crypto also doesn’t take power away from institutions. [...]

Gotta disagree with "crypto doesn't take power away from institutions". Exactly as you said, if institutions leverage their pre-existing power in the crypto space, it becomes centralized because a small pool of wealthy players control the majority of the currency. The currency itself is not centralized, but it can be exploited by bad actors who wish to manipulate its value (or just profit off of it, either way). If existing institutions weren't using their massively accumulated wealth to affect the crypto space, they would be losing power over the people who decided to avail themselves of it and bypass conventional banks. I consider this a weakness in cryptocurrency that needs to be addressed, but is this weakness any different from any other currency?

Crypto is also incredibly power inefficient. Even with proof-of-stake instead of proof-of-work, it is still factors less efficient than normal FIAT transactions, and as of yet I see no solution to that. One may pop up in some hypothetical future, but I have no faith in that.

Zero arguments from me. It's an environmental disaster.

Additionally, crypto will also always reward those who engage with it disingenuously, as it is not linked to one’s real identity and, again, is inflexible and impossible to truly regulate. In a mass-adoption scenario, scammers would become enormously more successful.

Depends on how you intereact with crypto. In the US, most states require crypto brokers to verify the identity of those trading on their platforms. No different from opening a checking account with a bank. Sure, one could get into crypto anonymously but it's considerably harder. Some crypto ATMs exist, but I think virtually all of them have cameras and require you to show photo ID to use them (at least in the US).

Most importantly, crypto is a digital asset whose store of value is implicitly tied to the belief that it can be sold for FIAT. It is almost exclusively a speculative vehicle, and always had been since its inception. Actual crypto purchases are disincentivized by how slow, inefficient, unwieldy, and volatile it is. Not to mention high transaction fees for the most popular coins. It is also deflationary, meaning one is disincentivized from spending it, which is extremely bad for the economy in a mass-adoption scenario. Gentle inflation is one of the core principles underpinning our economy. Having currency also be an asset that appreciates in value is objectively a bad thing.

I disagree that it's been a speculative vehicle since its inception. It's undeniably a speculative investment now, and has been for years, but when it first started out, it was basically worthless and adopted by a handful of businesses who were understandably pissed off after the 2008 market crash. People naturally speculated as to whether or not it would take off, and I think it's unfortunate that it became a speculative investment by those who weren't really interested in its use as a currency.

I'm no economist, but I don't see much difference between "crypto's value is implicitly tied to the belief that it can be sold for FIAT" and "FIAT's value is implicitly tied to the belief that the issuing government values it"

I feel like I could keep going for a while but hopefully you at least understand why I feel this way now lol.

Oh believe me, none of this is news to me. I just wanted to see what you thought. I've found the cryptocurrency conversation interesting as the years have passed and enjoy asking people for their thoughts when they appear to be engaging in good faith. Most people I see are very unpleasantly hardline for or against crypto and don't care to take time to discuss any of the nuance.
