comprehending space

in all honesty I bet a lot of people wish they had a easier way to carry load or unload heavy or a lot of items soo yea it sounds amazing but imagine you having a device that breaks down those items at a molecular level and stores it until your ready for those said items its basically invoking a storage feature into an item so my theory comes into effect here ...

if humans could understand molecules and atoms and cells and everything on a molecular level it would advance civilization by leaps and bounds and could even be used for endless possibilities but one question what would You the readers use it for? I mean you could already use it for godly reasons lol don't want to risk a car theft or break in or risk a burglary or afraid of your money being robbed? bam a storage only you can use and is registered to you by DNA registration ahaha it may sound insane but it would be marvellous
