Those are standardized containers standardized which are made in the millions as cheap as possible. That stuff needs to work, think of all the means of transport where it is used (vessels, trains, aircraft), be accessible for inspections (customs) and so on. The costs to secure and upgrade the containers for the whole system is probably a lot higher than accepting a small percentage of stolen parcel.
