All humor and pithy quips aside. The assumed liability is very different. A driver of a commercial courier accidentally transporting an illegal substance is at much less personal risk than an average citizen or small business.

I think this match-maker platform should be willing to shoulder more that liability. KYC but for bill of lading as well?

While not 1-1 or perfect, AirBnb and TaskRabbit platforms include insurance and other risk mitigations for both sides of p2p relationship.

You think the average person has the infrastructure and the relationship with customs and the DEA that FedEx and ups do?

Yes because if someone gets stopped carrying contraband who works for FedEx, delivering in a FedEx truck, wearing a FedEx uniform is going to be treated the same as Bob in his Honda Civic who said he picked up a package from a known trap house and had no idea what was in it.
