I mean that when I've asked people what utility they get out of blockchain they mention the ability to send BTC overseas quickly and easily, to countries in which it's difficult to send money. I assume they're not lying about that use case.

In practice transferwise (now wise) is able to transfer money more easily and with much lower fees. At least if your needs match normal consumer needs.

This switches if you need to transfer millions of dollars, or you're trying to pay for something illegal. Which is why one of Bitcoin's significant real-world uses is for ransomware. It does indeed make it easy to launder millions of dollars of money across national boundaries.

In practice there are things such as country-wide sanctions that make "regular" services not particularly reliable in some cases.

So the utility of crypto is to violate sanctions?

Among other things, sure. Given how many of them are in place for no good reason (e.g. Cuba) while significantly hindering quality of life for innocent people, I consider that a net positive.

The utility of crypto is to transact without restrictions yes.

They send nothing as BTC is not located anywhere. They buy and sell btc with fiat currencies, that is all.
