Decentralized lending via Ethereum smart contracts is now a real thing. Check out this out in a dApp browser like Coinbase Wallet: https://app.compound.finance/

I’m current earning 3.5% apr by lending out USDC (Coinbase’s stablecoin) via dApp.

EDIT: I guess I am being downvoted because people think this is spam? I only have a disincentive for people to use this dApp: as more liquidity gets added to the pool, my payout interest rate goes down.

To be fair, "I give out vague loans in internet money" doesn't naturally default itself to being a good thing, and namedropping "smart contracts" and assuming that means anything aside from spam&scam technobabble to people outside of the ethereum is a bit of a miss on your part.

Protocols like Secure Scuttlebutt provide decentralization without any cryptocurrencies or global blockchains. It's a bit of a wild west, but I don't think that's a bad thing.

Cryptocurrency is freedom from intermediary interference. That's not a big deal in the US, but in some countries people can't even have bank accounts.

Hahaha, you keep telling yourself that. Some countries don't even have reliable network/power/etc and don't say "oh you can trade bitcoin with paper," because that's just stupid.

Sure, but there are enough countries out there that fall into both the "reliable enough connectivity" and "government control of money" parts of the Venn diagram that this is still valid.

And the world is only getting more electrified and connected as the years go on.
