Respectfully, I think it’s just you. Ethereum smart contracts are universally publicized and utilized in the crypto community, and it’s why people were/are interested in the project. Many other coins are built on top of this technology. It’s pretty foundational. If you look into crypto any deeper than just buying and selling it, then the topic should have come up pretty much immediately.

I reckon most of that already is. A real estate escrow smart contract is maybe 200-300 lines long in Solidity, depending of course on what it supports (contingencies and such). You may want to actually go look around, because there’s I don’t know how many millions of lines of Solidity already written. It doesn’t all get as much publicity as NFTs.
