You are using word "smart contract" like it's some magic spell. You can't make a contract with external inputs, from outside the blockchain. Or more precisely, you can't make a reliable "sc" with such inputs. And no, those people claiming to "solve" oracle problem didn't solve anything.

You can't have "smart contracts" applied to the real world without centralised entities controlling them. Therefore they are mostly redundant and unnecessary.

Regarding the size of the title - I admit I don't know much about that area, but I know enough to doubt your claim that majority or even any titles can be reduced under the kilobyte. Splitting info into multiple tokens will only make things even worse.

Also this doesn't address the issue that UX of centralised entity working with such system will be atrocious. You postulate that there will be no centralised entity, but imho that's pure fiction.

And lastly - IPFS will never be adopted for anything important because it doesn't have safety guarantees. Not even with those services promising guarantees for some regular payment. Because subscription can run out, that service may close or anything else can happen, IPFS still can't guarantee file safety. That's a nice toy, but nothing more in the current implementation.
