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.
