> could have been made with any "thing"

"any" is going a lot of heavy lifting there.

Apart from people agreeing on value, that thing also has to be: 1. out of their governments' control (all the examples had governments gone bad), 2. easy to transfer/carry, 3. durable.

Can you please name a few alternatives if you think that's a simple problem?

Bitcoin fits the bill for those aspects. Can you name a few other "things"?

Gold. Shells. Anything that people have used as money over the years.

I do not disagree that blockchain tech has a good use case. It's just that it does one thing: a distributed ledger. That's it.

"That's it" fails to capture the fact that said tech still has a collective market cap of $984B[1], after it has had precipitous drop in value over the last 12 months. Maybe, a distributed ledger for digital goods is a massively valuable tool for humanity?
