"The SEC’s Crypto Task Force is considering a potential exemptive order that would allow firms to use DLT to issue, trade, and settle securities. This potential conditional exemption from certain SEC registration requirements and associated rules would allow firms to use innovative trading systems for eligible tokenized securities."
Crypto makes it possible to find the right price (auctions, AMMs etc) and provide financial instruments (options, loans etc.) for a longer tail of assets.
For most end users this is too complicated to reason about. You just want a price for your desired object, not a complicated option and an auction.
However, if AIs are transacting with each other this "mental overhead" might not be a bottleneck anymore and they can leverage the full onchain financial toolkit.
