That also leads to my other (perhaps main) issue with this idea, which is that it requires some level of coordination or synchronicity with the delivery courier that's simply inconvenient for both of us. I've lived in apartments that 90% of couriers of any service cannot find their way around, because they weren't simple take-elevator-and-walk-to-unit designs, so I thanked the stars when we got lockers at the gate. Perhaps I could leave my packaging in a locker... but that just sounds like we re-invented trash collection? And actually, this is why I never used grocery services like Amazon Fresh or Instacart. I don't think grocery delivery is as solved as you think it is.

The implied time synchronicity also sounds like a nightmare. Taiwan does timed trash collection (you have to throw the bag into a garbage truck when it comes playing Fur Elise at 7pm) and there's a reason it hasn't spread.

I just think this is overcomplicating matters instead of just making the package generically disposable, which seems to be what's happening anyways.
