I'm sure one can learn/be taught (trained?) to be more aware of how often this is done. But, there is no immediate NEGATIVE feedback. So, nothing to discipline users against the practice.
Inca cold climate, stepping out of a warm house into freezing temperatures "teaches you" not to leave the door open. The same isn't true in a hot climate with a cool house interior.
We don't have that problem. E.g., I can leave a bowl of popped corn on the counter, overnight, and it will still be crunchy the next morning. This isn't true during Monsoon; but, that's a relatively short season (and not always very humid).
Hence "defrosting the freezer". Most frigs have heaters to automatically defrost the freezer compartment (hence ill advised to leave many things in that compartment for long periods of time).
Our "deep freeze" must be manually defrosted (has a built-in heater that you must manually activate). Despite being located in the garage (where the air has no "conditioning" wrt humidity), we only need to do this once each year. We time the activity for the point where the freezer is least full -- just prior to harvesting citrus juices (when the last year's harvest is just about gone). We'll store 100 qts of fresh-squeezed OJ, about 30 qts of lemon juice, a qt of lime juice (a little lime juice goes a LONG way!) in addition to the normal frozen foodstuffs. Things will be cramped (the chest fills to the top; you have to physically remove the baskets to access what lies below -- there is no room to "slide" them to the side, as intended).
Anything that isn't juiced or stashed in the frig is given to neighbors or donated to local food bank.
[We get about 300 pounds of fruit off each tree]
As we don't have "less used" interior spaces (e.g., basements), the garage is the only option for anything of size. I can't think of anyone who *doesn't* have at least one refrigerator and likely a freezer, as well, in their garage. Neighbor just remodeled her kitchen. So, the "old" frig joins the OLDER frig in the garage.
Again, there's little/no consideration for the added electrical load. Instead, it's seen as a boon: "Oh, good! I can store MORE stuff out there!"
Another friend has two frigs and a freezer in addition to his kitchen appliances. And lives alone (!)
E.g., it is fairly common to have a couple of cases of bottled water in a spare frig; you wouldn't want to waste all that space in your *indoor* frig but having a steady supply of cold water is seen as a win (personally, I think the idea of buying water in bottles is ridiculous).
Larger households often find a "normal" (20 cu ft) frig to be too cramped. E.g., two of us keep such a frig pretty full. Come Feb/Mar when the blossoms on the orange trees are too large to be ignored (and in danger of being knocked off the tree while harvesting fruit), we'll load the frig with a few hundred oranges. We will feel "cramped" for space, at that point, and our shopping habits will change (until we've had a chance to consume some of the harvest).
As with anything, it is very easy to become accustomed to "more" vs. "less". More food storage, more habitable space, bigger vehicle, etc. And, unless there is some pressure working against these tendencies, no real incentive to counter them. The convenience they represent is hard to ignore (e.g., tomorrow we'll make pizzas. No shopping for ingredients necessary -- just remember to take them out of the freezer early enough for them to defrost prior to lunch!)
