Arrow's Dictator Theorem asserts that any voting system with preference order as input and satifying his two axioms cannot be democratic. Instant runoff voting system has preference order as its input and satisfies the two axioms, hence, it cannot be democratic. The crucial thing about the Fractional Voting System is that it has preference *distribution* as its input.
STV is used for both single-winner and multi-winner elections as this quote from Wikipedia indicates: "When STV is used for single-winner elections, it is equivalent to the non-proportional instant-runoff voting method. To differentiate them, STV used for multi-winner elections is sometimes called proportional representation through the single transferable vote, or PR-STV." Incidentally, I looked at your channel, it is great, the kind of work all of us should be doing. Thanks.
I'm not really sure how instant runoff voting would not work to meet all the conditions of Arrow's Paradox...

Single transferable vote is a system that elects several people at a time. You are talking about a different system!
