Simplify the system!
When you check in, your luggage is tagged and scanned and passes DIRECTLY to the "Security Checked Departure Area". The passengers are similarly 'security checked' and can be reunited with their luggage in the same place (admittedly, there's room for cock-ups here) where they collect their own bags and take them to the gate themselves, where they are collected at boarding and loaded directly onto the flight. Think of how many surly, lazy, belligerant, sticky-fingered baggage handlers could be dispensed with. And at least you'd have a better idea that you would have more than the clothes you're standing in when you get to the other end.
Of course, having ALREADY SPENT a fortune on a 'cutting edge baggage losing, sorry, handling system'...
And natch, there's 'such as those' for whom the theory of having to carry your own bags is utterly abhorrent.
