Why is this a problem? You can't file a flight plan electronically?
And get the FAA to respond with your waiver in under 5 minutes? The point of these flights is the under-30-minute delivery. That includes handling the transaction, picking the product at the warehouse, getting it on board and in the air and several miles away. The FAA isn't built for waiving NFZ rules in minutes.
Regardless, you're ignoring the whole no-BLOS part of their regs. They require a certified PIC and a spotter with eyes on the vehicle the whole time. It's taken them years to decide about THOSE rules. Deciding to waive them will take years more if ever.
