Regarding missed packages, are you talking about stolen packages? I've had a few cases where delivery was one day late and one time I got the wrong order (but got to keep the free groceries along with a full refund for my actual order) but I've never had a package just disappear altogether. Even Aliexpress orders that take 2-4 weeks from China eventually show up.
I've had a single-digit number of packages never delivered, most of them years ago, from Aliexpress (which, at least back then, had a very buyer-favoring dispute process, so I would get my money back with three clicks or so).
Only if I really needed that specific thing pretty badly today would I spend a few bucks and 20 minutes to drive over to come get it.
I ordered some physical thing, not that thing and a quest.
In the US all carriers drop packages at door (or in the building's locker if you live in an apartment complex). Some packages need to be signed (alcohol, nicotine, gun ammo, etc) but the vast majority of deliveries involve zero human interaction
Then why so much effort is needed to stop package theft to the point of giving access to your house to strangers? Apparently getting package on your doorstep is not as convenient as you would like others to believe. Using such lockers is convenient and secure, giving package to recipient hands is secure but not convenient, leaving package at doorstep* is neither.
*or any other place convenient for whomever is delivering it
