Technically linked lists can be between different data structures, other than "blocks." Blockchains are chains of blocks, not chains of skiplists or whatever you're doing with linked lists. And I'm not basing it off of anything. Regardless of what you think is proper for calling something a blockchain, and whether I should be allowed to refer to non-consensussy blockchains as blockchains, there are intractable problems with blockchains as I define them, even if they lack that Byzantine consensus nonsense.
