You're absolutely right BUT I do want to point out a situation where the answer is "Yes" because the model is entirely different.
Last mile delivery is expensive because it does't enjoy the economies of scale.
I'm increasingly seeing increasing number of random personal vehicles drop off my retail packages that were shipped via UPS/FedEx to a central hub. I don't understand why these retailers even do this - these items are like $1-$10 and part of a much larger order that arrive in a staggered fashion. I would imagine people pay more than the item in just gas so it's likely a customer satisfaction thing.
I imagine either the retailer or UPS/FedEx indemnifies these people if and when things go wrong so these people have the backing of a multibillion dollar logistics company. Perhaps the OP could look into this portion of delivery? The OP is really light on location and painpoints to ave a real concrete conversation.

I have also seen this, but I’m pretty sure these people are essentially employed as delivery personnel, and their cars are acting as small delivery trucks. I’m not sure how the cost for this work out. Maybe FedEx/whoever is closing the gap when they can’t get everything onto real delivery trucks and this is more cost effective than buying more trucks and hiring more drivers?
I think last mile is an interesting problem but OP seems to be intending to build full transit logistics infrastructure built on casual labor, which seems unlikely to pan out.
