Why would a blockchain be better than a traditional database for this? Making it decentralized is a non-goal, so what would the advantages be?

The real issue is not the specific technology, it's that it's an ancient hodge podge.

No. The issue is that you have no central ledger of ownership of stock, but instead many firms' individual ledgers. You also have various kinds of risk of fraud, etc.

T+2 is an atomic commitment algorithm that leaves enough time for humans to make phone calls and discuss the implications when there's going to be a failure to deliver or another anomaly from fraud or globally inconsistent state.

It's far more centralised than you think, dematerialization isn't 100% complete but Cede and Co. hold the ledger of who owns what - at least to the extent that is possible.
