I tend to not load everything up, but I have a good inventory of supplies, components, and loaded rounds.
Cartridges that the loads do not change, I tend to keep more loaded than those that are still varying. When inventory runs low, I'll crank up the progressive and make a good run.
There are times that I stop shooting a particular cartridge for some reason or another. If I have a good inventory, I see no need to load up the empties to just have them sit idle. The components might be useful for other cartridges. For example, I do not shoot much 357 Magnum these days and am still working off 10 year old reloads. I still have several hundred 357 Magnum rounds i inventory. I can use the primers and powder that I load in 357 Mgnum in other cartridges that I am actively shooting currently.
I do resize, clean and prep all fired cartridges shortly after shooting them, whether they will be reloaded soon or not. Then, they are instantly ready to reload should the need arise. Also, I find prepping cases shortly after firing goes quickly because the batches are relatively small. If I wait until I have boat load of cases to process then it becomes drudgery.
