The knowledge that route (a) was originated by AS (x) is only meaningful insofar as one has some set of high-confidence beliefs/expectations about AS (x). However, if AS (x) can change hands at will, henceforth no such confidence will be possible for the overwhelming majority if not all ASes.

If the ASN was transferred and trust mechanisms were implemented,
wouldn't the trust chain break?

I don't quite understand what the problem you are describing actually
is. If someone transfers an ASN to "steal" peering, it would take a
lot more work than just that. At a very high level, the entire
relationship would change and probably dramatically from what it was
before the transfer.

How about a real world example of how transferring an ASN has hurt someone?
