Maybe eventually. Right now, there's a whole lot of problem with scaling for distributed ledgers. Big markets do 20M trades per day-- and that's just across the market itself.. This is like 50k TPS average (not peak) across a trading day; some distributed ledgers do better but compare to several transactions per second across Bitcoin and a few thousand TPS per second for most performance-oriented ledgers.

You might also not want to have a public ledger of all the ownership interests.

It also doesn't exactly solve the problem. You still have the prospect of double spend, etc, until commitment/ledger settlement. And for high stakes transaction you probably want humans in the loop talking about what to do when these things happen instead of some automated policy.
