This is what I have been saying since LLMs came out.

A device with a custom agent that has a screen, mic and speaker can now turn amazon into a logistics company.

The most low friction way of doing anything is to just ask someone else to do it for you. In this case it's the agent. So now if a company wants to capture a percentage between the buyer and seller then they need to have influence over the agent or capture a percentage of the transaction fees.
