> They don't even have an on-chain hash of the digital asset

Yea... 45% of NFTs have their hash on chain https://yournfts.org/#stats. It isn't great but it isn't none.

Interesting point from the same source:

> For example, OpenSea serves most of the NFTs they mint over HTTP. If the OpenSea ever collapses, ~8% of NFTs vanish.

The NFTs will still exist and be tradeable outside of OpenSea even if OpenSea itself disappears because they live within a smart contract.

They will point to nothing and hence (hopefully) be worthless

Yep, exactly. Opensea hosts most of their minted NFTs on HTTP.

Open seas contract code is not open AFAIK (binary is obviously available but I have not seen source other than decompile) Many contracts can be updated by leveraging proxy contracts. They can delete your nft if you mint with their contact.
